David was a man of culture.
Not the kind who went to museums or read fancy books. No, David appreciated the fine art of 18+ visual novels. He didn't just play them—he devoured them. Every route, every bad ending, every steamy CG. He was thorough. Obsessive even.
So when he finished Love x Lust: Summer Sins, a modern Japanese dating sim with extra content, he expected fireworks. Drama. Maybe even tears. Instead, the main character ditched the most interesting girl and picked the basic childhood friend. Just like that. No warning. No soul.
"Are you serious?!" David shouted, flinging his phone onto the bed. "All that buildup and she gets friendzoned?"
He fell back on his pillow, arms crossed. His eyes burned from staring at the screen for hours. His brain was fried from too much... "plot." He closed his eyes, grumbling about bad writing and wasted potential.
"I could've written a better ending," he muttered before dozing off.
David woke up sweating.
Not from a nightmare. Not even from the guilt of spending five hours on a yandere route.
No. It was because this room was not his.
He sat up fast. The bed was soft. Too soft. The ceiling was clean. The air didn't smell like old socks and instant noodles. He was in a room he'd never seen before. A neat desk sat by the window with a school uniform folded on top. Summer light poured through half-open curtains.
"What the...?"
That's when it hit him. Not a realization. A voice. In his head.

Reward: ???
Failure: The story continues. So does the 'plot'.
David blinked.
Then blinked again.
"…No way."
He jumped off the bed and ran to the mirror across the room. A young man stared back. Messy dark hair. Slim but built. Clear skin. Stylish glasses. No acne. No dark circles. No gamer back-hunch.
He adjusted the glasses. They glinted dramatically.
"I'm… hot?"
The system dinged again.
Daily Task: Prevent a summer event
Optional: Acquire Swimsuit DLC (Effect unknown)
David stepped back and sat on the edge of the bed, trying to breathe.
"I got isekai'd into a h*ntai game," he whispered. "I'm in the damn background of a dating sim."
It wasn't a normal game world. It was that game. The one with accidental gropes, steamy locker scenes, hot springs "misunderstandings" and more bouncing than a beach ball in July. But despite the lewdness, it had a story. One that, apparently, he now had to mess up.
His first mission? Stop the protagonist from meeting the main girl, Airi Minase.
Airi. The sweetheart with the short skirt, killer smile, and massive... plot armor. She was supposed to meet Yuuto, the main guy, during summer break. Classic cute girl trips and accidental kisses. But now David had a month to ruin the opening scene.
He looked down at the uniform.
A normal school guy. A mob character. He had no stats. No powers. Just glasses and knowledge of the story.
"This is so stupid," he said.
Outside the window, someone called out.
"Morning~!"
A girl walked by the gate of the dorm. Short brown hair. Tight white shirt. A skirt that didn't know what modesty meant. She waved up at the window. David's window.
It was her. Airi Minase.
He ducked.
"Oh crap oh crap," he muttered. "That's the scene! That's the first flag!"
In the game, Airi walked by the dorm, the protagonist came out to throw trash, they bumped into each other, and boom—romance starts. If David remembered right, this was the "Sunburn and Watermelon" route.
He peeked again. No sign of Yuuto yet. That meant he still had time.
Think. What would a cultured man do?
Distract her? Fake an emergency? Pretend to be Yuuto? Sabotage the trash bag?
He had to act fast.
David scrambled for his phone. Nothing. No apps. No internet. Just the system menu and one blinking button that said "Use Item: Ice Cream Stick."
He tapped it.
Outside, a small drone flew over Airi's head and dropped a popsicle right in front of her. She gasped, looked up, and ran after it.
"What the hell was that?" David whispered. "That worked?"
Event Prevented
Flag avoided. You win this round.
+1 Point: Chaotic Interference
New Item Unlocked: Fake Spider
Keep going. The Harem must fall.
David leaned against the wall, heart pounding.
So this was his life now. Ruin love. Block s*x scenes. Delay dates. Basically be the world's biggest anti-wingman.
He smiled.
"Alright then, you dumb pervy game. Let's see how you like getting played."
