The Boundary Between Day and Night

[A teasing, elusive heroine who plays hard to get vs. a possessive hero who goes crazy trying to claim her]

For the year after meeting Gu Chenli,

Si Cheng treats him only as a tool to regulate her hormones.

But after spending so much time together and letting sparks fly,

who can promise to keep their heart untouched forever?

On her birthday, Gu Chenli corners Si Cheng in a secluded spot in the banquet hall.

He takes her hand and presses it against the scar on his back.

"Give me a little of the kindness you give everyone else. Don't leave me so lonely, okay?"

When a ruthless kingpin falls into faithful love,

he's scarier than a mad dog.
