“Claim the item? Yes/No”

Without hesitation, Shirakawa Natsu clicked “yes,” and a flash of light appeared on the phone screen, causing the 3D version of Hashimoto Arina to disappear.

“Congratulations! You have obtained a randomly unlocked item from the shop: Stamina Potion. It has been added to your inventory.”

Two new features appear in the bottom right corner of the screen: Backpack and Encyclopedia.

Opening the catalog, the first image is a photo he secretly took of Hashimoto Arina when he first imported it into the app. However, after being processed by the app, it is even more lifelike, and its realism has surpassed the concept of a photo.

The first page of the encyclopedia has six slots. Except for the first one, Hashimoto Arina, the other five are grayed out and unlocked.

Below Hashimoto Arina’s portrait and the second gray portrait, there is a line of small text: “Special mission trigger conditions have been completed (1/2)”.

Shirakawa Natsumi’s expression turned strange upon seeing this; this was clearly a special mission that could only be unlocked after successfully winning over the two female protagonists.

The “Yellow Hair APP” requires two female protagonists at the same time, and when these pieces are put together, things suddenly become strange.

Shirakawa Natsumi was absolutely certain that he had no expectations whatsoever.

He glanced at Hashimoto Arina, who was nestled in his arms with her eyes closed and a happy smile on her face.

She made a silent vow in her heart: “I swear on my name, Shirakawa Natsu, even if I jump off this building and get hit by a car outside, I will never let Hashimoto Arina lie with other girls and do those sadistic things together!”

He calmed his increasingly rapid heartbeat, closed the encyclopedia, and opened the shop. The points section in the upper right corner of the shop interface had changed from zero to one hundred.

The stamina potion, which was originally placed alone on the left, now has a gray button next to it that has been unlocked.

It was an ornately designed heart-shaped symbol. “Special Item: Fated Lover, which can keep the target’s affection level towards you constant at 100 for 12 hours.”

“Note: This item cannot be purchased with points. It is automatically obtained when you choose the difficult lover for the first time. Other acquisition conditions are unknown.”

“Difficult Lovers?” Shirakawa Natsu continued clicking, and sure enough, she could open the notes again. The creator of the Yellow Hair App must be an angel, making it so thoughtful.

“Difficult Lover: Unlocked after completing the first task. The app will automatically calculate the difference between the user’s own comprehensive value and the comprehensive value of the selected lover. The points earned from the romance will be different: Easy (60%), Normal (100%), and Difficult (160%).”

“Tch, anyone who chooses the hard difficulty is an idiot.” Shirakawa Natsu lost interest after just one glance. He would definitely choose the easy difficulty, even if it’s only 60%, which is 60 points. It doesn’t matter, as long as he grinds enough, he can grind to level 300 by fighting slimes.

Shirakawa Natsu opened the shop to see if there were any items that would make it easier to obtain health, and after confirming that there weren’t any, she quickly closed the shop.

Clicking on the last status bar reveals a page he has opened countless times late at night.

The familiar outline of a male human body is depicted, with lines and dots used to mark various body parts, such as the heart and kidneys.

Her heartbeat, which had been calming down, started racing again, and Shirakawa Natsu trembled as she tapped her heart with her finger.

“Should we upgrade to the Strong Minotaur Heart?”

“Note: This is a powerful and explosive healthy heart that will provide you with endless power in battle.”

“Required redemption points: 100 points”.

“yes.”

As Shirakawa Natsu tapped her finger, the heart made of lines on the screen suddenly came into color.

“Thump!” A heavy, powerful heartbeat resounded from his chest.

The throbbing seemed to tug at his soul; his body began to tremble, and an incomparably powerful force spread throughout his entire being.

“Really, I’m back to normal!” Shirakawa Natsu clutched his chest; he had almost forgotten what it felt like to be healthy.

There will be no more sudden angina, no more sudden suffocation.

People only realize the value of health when they lose it. At this moment, his eyes were red and tears were welling up in his eyes.

His body was trembling uncontrollably. All his efforts had finally paid off at this moment, and he had finally regained his health.

Hashimoto Arina, who was beside him, sensed something was wrong with him. She opened her eyes slightly, reached out and gently stroked his cheek: “Natsu, don’t think too much. Being with you is enough for me.”

“Arina-nee.” Shirakawa Natsuya reached out and hugged her soft body. He knew that Arina was worried that he would be frustrated by his performance in the previous two minutes.

But he is no longer the same person he was just now. The two minutes are completely in the past. After receiving the minotaur’s heart, he feels his whole body is filled with inexhaustible power. Next, he will let Ayane feel his power.

Hashimoto Arina was taken aback, feeling his waist moving back and forth. Her face flushed, she gave him a reproachful look, then closed her eyes and slowly began to enjoy it.

Shirakawa Natsu rolled over, pinning her beneath him, and lowered his head to gently kiss her fair neck.

Hashimoto Arina slightly opened her legs and gently wrapped her arms around his waist.

Two minutes and thirty seconds later, Shirakawa Natsu lay on the bed, staring at the ceiling. At this moment, he no longer had any worldly desires.

This state allows him to calmly consider why, even with a stronger heart, his time only increased by thirty seconds.

The heart’s function is to supply blood to other organs in the body, while the kidneys are like an old car riddled with holes.

Even with the fuel tank full, the functional limits are still imposed.

“Next time, I’m definitely going to upgrade my kidneys.” Shirakawa Natsu made up her mind. She glanced at Hashimoto Arina, who was still sleeping soundly, her fair arms exposed. After the battle just now, she hadn’t even broken a sweat.

Shirakawa Natsu had originally left behind that bottle of stamina potion, but men are always irrational, especially when a beautiful woman is lying on her side.

Open the app, tap on the back, and there lies a bottle of medicine quietly.

The potion was administered, but instead of appearing in reality, it was directly applied to him.

Shirakawa Natsu felt an unprecedented surge of energy coursing through her body, an energy she had never felt before, even when she was in good health.

I felt like I could kill a bull with one punch; every cell in my body, like a sponge absorbing power, began to gradually expand.

Hashimoto Arina liked Shirakawa Natsumi inside her body, and immediately felt something was wrong, so she slightly opened her eyes.

Shirakawa Natsu reached out and hugged her slender waist again.

“No, that won’t do.” Hashimoto Arina placed one hand between the two of them. After the three exchanges just now, the shyness on her face had lessened. “There’s still a long way to go. Natsu needs to take care of her health.”

“Just once.” Shirakawa Natsu was too lazy to explain. He looked into her eyes and gently placed his hands on her waist.

Hashimoto Arina only stared at me for a moment before giving in: “Honestly, looking at me like that, even though you know I won’t refuse.”

After she finished speaking, she closed her eyes slightly.

Hashimoto Arina was very passive in these matters; closing her eyes allowed her to feel the changes in her body more.

Shirakawa Natsu liked to watch her expressions and would react in different ways to his every move.

She closed her eyes, moved her body slowly up and down, and her breathing gradually became rapid.

Gradually, breathing through the nose alone was no longer enough to satisfy the needs of the abdomen, so the mouth was slightly opened and a breath was exhaled.

His body swayed and floated more and more violently, and his breathing began to turn into suppressed groans.

Hashimoto Arina also sensed something was wrong. She opened her eyes while panting and met Shirakawa Natsu’s gaze.

Her eyes gradually became glazed over, beads of sweat appeared on her forehead, her body went limp, and her mouth opened slightly as if she wanted to speak, but her breathing made her words unclear.

Shirakawa Natsu noticed that Hashimoto Arina’s behavior was not consistent with her usual older sister persona.

In these matters, they appear particularly passive, powerless, and at the mercy of others.

Sweat began to appear on her fair skin. She gently supported herself on Shirakawa Natsu’s chest with her hand, though she had no strength in her hand. Her eyes were glazed, and she was panting, saying, “No… stop, let’s rest.”

“No, the most important thing in life is to keep your word. If you say you’ll keep your word, then you’ll keep your word.” Shirakawa Natsu said, turning her over so that she was lying face down on the bed, and holding her slender waist, which was smooth and soft due to sweat, in his hands.

After an unknown amount of time, Hashimoto Arina woke up from her daze, feeling a wave of fatigue wash over her, as if she had been working overtime for a week straight.

My body felt sticky, and the sweat made my skin stick to the sheets, which felt uncomfortable. Even lifting my arm was difficult, and my legs were so stiff that I couldn’t move them.

My brain, which had been shut down, gradually resumed thinking, and I began to organize and analyze my previous memories.

“Natsu, I think I had a dream.” Hashimoto Arina opened her eyes, and as soon as she opened her mouth, she felt something pressing against her soft lips.

“With Sister Cai, it’s not a dream.” Shirakawa Natsu was half-sitting, and he shrugged: “Let’s come back after the halftime break.”

Hashimoto Arina’s expression froze, her mind clearing in an instant: “No, I…”

Before he could finish speaking, the rest of his words were forced into his stomach.

The next day, after taking a bath, Hashimoto Arina walked unsteadily, but insisted on making breakfast herself.

Shirakawa Natsu felt a surge of tenderness in her heart as she watched her trembling figure busily working at the stove.

He quietly walked behind Hashimoto Arina, reached out, and tried to put his arm around her waist.

Hashimoto Arina reacted even faster than him, turning around abruptly, gripping the knife in both hands, her face slightly flushed: “Natsu, go sit down at the table.”

“Calm down, Sister Yu Cai!” Shirakawa Natsu quickly raised her hands in surrender: “I just wanted to hug you from behind, please put the knife down.”

“Liar!” Hashimoto Arina pouted. “Don’t think I don’t know what you’re thinking. You want to take this opportunity to pin me down on the stove.”

Shirakawa Natsu was taken aback, her expression gradually becoming strange as she looked at Hashimoto Arina in her cozy home clothes, and then at the closet.

Sister Cai knows a lot.

Under his gaze, Hashimoto Arina’s face flushed even more. She put the kitchen knife back in the cupboard, turned her head away, and dared not look at his face: “Next time, it still hurts now.”

“Okay~” Shirakawa Natsu suppressed a laugh, turned around and sat back down at the dining table, as if she had inexplicably unlocked a new scene.
