[Younger man + obsessive love + groveling to win him back]
Gu Liangchen’s original plan was simple: tempt Lin Shi, seduce Lin Shi, then dump him brutally once Lin Shi had fallen hopelessly in love with him.
Gu Liangchen sets his revenge plan in motion, calling Lin Shi “baby” this and “baby” that, asking if he’s warm enough today.
Sure enough, Lin Shi falls for him.
Great. Next step: dump him!
Right, dump him! Right... well... not before...
Right! Before that, he has to chase away all the pests around Lin Shi! Leave him isolated and helpless! Make sure he has no one to rely on! Yes! That’s it!
Gu Liangchen puts his plan into action. He holds Lin Shi close, pecks at him like a woodpecker, and drives away every close friend around him.
“Senior, senior... You’re mine.”
Gu Liangchen insists this is all for revenge.
He says he’s going to dump Lin Shi, but Lin Shi is the one who leaves first.
Gu Liangchen loses his mind. He grabs Lin Shi, locks him in a room, and waits on him day and night, speaking to him as gently as he can.
His eyes redden and his voice turns hoarse. “...Senior, you’re abandoning me again.”
P.S. The story opens with confinement in a locked room. The blurb takes place a little later.
