Reborn, the System Makes Me Court the Villain

The unluckiest thing that ever happened to Chi Yang was finding out, at the age of twenty-four, that he was a disposable side character in a novel, whose sole purpose was to provide contrast for the destined male lead's backstory. When the Chi family discovered he had been switched at birth, they threw him out. His biological parents wanted nothing to do with him either. He struck out at every turn in his job search, and just as he finally started delivering food with the big brother next door, he was hit by a truck running a red light on his third day at work.

Then he was reborn.

He was also bound to a little orb of light that called itself the “555 Wish-Granting System.” The little thing ordered him fried chicken and cola, then said earnestly: “Host, you are the source of this world's collapse. Because you died, the great villain Yan Chuan tore the entire world to pieces.”

Chi Yang froze mid-bite. “...Who?”

The System replied, “Yan Chuan, your high school deskmate and head of the Yan family in the capital.”

Chi Yang: “...That sharp-tongued deskmate who called me stupid every day?”

The System nodded gravely. “That's the one. For world peace, Host, you must cling to him within a week.”

Chi Yang: “...”

This is a sweet, satisfying romance about an adorable little goofball who's always a beat behind and his love interest, a man who seems icy on the outside but is already a complete lunatic inside. For the sake of world peace (crossed out), the two keep pushing and pulling as they fall in love.
