Trapped as an NPC in a Dating Sim

oren transmigrated into Lover’s Labyrinth, a dating sim, not as a protagonist, but as a side character. That should have been fine. But instead, he awakened the Perverted Harem System, which gave shameless quests so absurd that even thinking about them made him seethe in anger. “This is a dating sim, not a pornhwa,” he roared in rage. From academy life to dungeon trials, his peaceful plan began to collapse as the system dragged him into chaos, embarrassment, and dangerously effective “accidental” progress. If he wanted to survive one event after another, he had to complete indecent missions without getting himself killed or exposed, all while simultaneously building a perverted harem of heroines far stronger than him. Surely… nothing could go wrong. Right?
