Author : 林盎司
Shen QingShu, 22, died in an accident. His biggest regret before his death was that he'd been single all his life. He obviously wasn't a monk, but he'd never eaten meat.
Then, when he opened his eyes, he saw a handsome, self-assured man standing before him. The handsome man parted his thin lips slightly and asked, "Wanna have a one-night stand?"
Shen QingShu didn't hesitate at all. "Let's do it! Twice!"
The next morning, Shen QingShu woke up aching all over. Only then did he discover he'd transmigrated into a book. The handsome guy beside him who'd gone two rounds with him was the protagonist gong, Han Cheng, the second son of the Han Group.
And the original owner of this body was just a disliked, death-seeking cannon fodder.
Shen QingShu: ...Well, this is f*cking awkward.
But Shen QingShu didn't panic. Anyway, he was just a cannon fodder. He figured they'd part in a few days
He knew he was a tool man, a character who only existed to develop the plot.
-Half a year later-
Shen QingShu looked at the man next to him and wondered: It's been more than six months. Why hasn't he left already?
Until the day he saw the protagonist shou and Han Cheng meet by accident.
Tool man Shen QingShu immediately felt the call of duty. Eyes shining, he prepared to push the plot forward.
"Don't come looking for me in the future." Shen QingShu was extremely self-aware.
Han Cheng was shocked. "Why? Do you have feelings for someone else? Who is it?"
Shen QingShu: ... Darling, this reaction isn't quite right.
