Affection and Corruption Roll Back Together

Fang Lin is an invisible nobody at an elite academy.

He doesn't want to date or cause trouble. He just wants to study hard and get into a top university.

After acquiring a rewind System, he consciously uses it to avoid minor mishaps that might make him cross paths with the F4.

After running into F1 while feeding a cat, he rewinds and doesn't go feed the cat.

After discovering F2's vulnerable little secret in the library, he rewinds and doesn't go to the library.

After meeting music-loving F3 in the practice room, he rewinds and gives up practicing.

After running into runaway F4 at his part-time job, he rewinds and asks his boss for a day off.

Fang Lin does his best to keep his life peaceful. But the whole school notices that the F4 have inexplicably started falling for an invisible nobody.

...Turns out their affection keeps stacking up even after he rewinds. Why didn't anyone tell him sooner?

Fang Lin stops rewinding. All he wants now is to graduate as soon as possible.

Then, one day, the coldest and most arrogant F1 uses underhanded tricks to sabotage his plans to leave school.

The gentlest and purest F2 ties up the hand he uses to rewind.

The brightest and liveliest F3 pins him down in a classroom and kisses him fiercely.

The quietest and most loyal F4 wants to shelter him in a tower where he'll see no one but him.

Fang Lin: ...

Nobody told him the blackening scores stack up, too.

The protagonist has an exceptionally deadpan, detached personality.
