The Endless Loop of Love

Yi Cheng accidentally binds to the Green Tea System. To complete its missions and successfully come back to life, he has no choice but to desperately farm favorability with the school heartthrob, only to be told that the guy is cold and aloof, keeps to himself at school, and doesn't have a single friend.

Yi Cheng expects him to be hard to get close to, but after spending time together, he discovers the heartthrob blushes at the drop of a hat, even turning red at the ears, and speaks in a soft, gentle voice. He's as weak as a kitten, and a total shut-in, too. This only reinforces Yi Cheng's belief that they're just friends. From then on, he becomes an emotionless green-tea quote-spouting machine:

"Hey, handsome, wanna check out the four-pack I've been working on?~"

Don't say yes! Hurry up and say no!

"Hey, handsome, I'm so cold. You're so warm. Could you hold me a little tighter?"

Don't come near me! Get lost!

In front of other people, Han Yi is a cold, aloof top student who keeps everyone at arm's length. By Yi Cheng's side, he's Yi Cheng's caring little sweetheart, a clingy human sticker who follows him wherever he goes.

Han Yi thinks he'll be Yi Cheng's brother for the rest of their lives. But one night, after getting drunk, Yi Cheng throws himself into Han Yi's arms, cheeks flushed, wraps his arms around his neck, and coos:

"Senior, will you kiss me?~"

Just as he's about to get together with the school heartthrob, with only a confession left to go, he dies again!

When he opens his eyes once more, he's gone back three years!*

"Boss, Yi Cheng has been stuck in the Love Loop System you threw him into for three days."

"Has he fallen in love?"

"He died again."
