Surviving in a Yandere RPG

Ning Ling is super poor and unemployed straight out of college, so he makes a contract with the System.

He agrees to travel as a mission-taker to worlds based on RPG games and complete their quests. Once he finishes, he could receive a prize of up to one hundred million yuan!

He thought it would be an ordinary romance RPG. Ning Ling, who calls himself the god of galgames, figured earning one hundred million would be a piece of cake.

He never expected this world to be a "philosophical" one with men on every side.

Speedrunning the game seems impossible, and quitting would leave him saddled with a huge penalty.

After weighing his options, he decides to grit his teeth and clear the game, only to discover that every NPC around him is more than meets the eye:

[No. 1, a sunny and cheerful boy who often gives him thoughtful little gifts, but climbs through his window at midnight to keep him warm.]

[No. 2, a gentle, capable homemaker of a man who fusses over him and provides food and lodging, but suffers from severe delusions and refuses to get treatment.]

[No. 3, an upright lawyer who provides him with round-the-clock advice and even prepares a "philosophical three-piece set" for him.]

And there are No. 4, No. 5, all the way to No. N. More for the same price: one mission, satisfy them all!

Ning Ling is utterly despairing. In this yandere world, how is a normal person supposed to get out of here?!!!
