I Became a Cannon Fodder in an Interstellar Novel

Shen Yuan is a sweet, clueless boy sent into small worlds to complete missions.

System: Big shot, become friends with Wen Feier!

Shen Yuan tilts his head. But he's my boyfriend.

Later, the two really do become boyfriends.

But Shen Yuan doesn't understand why two people who say they hate each other end up passionately kissing against a wall.

Then Shen Yuan realizes that everything was a ruse by the System.

The mission is judged a failure. Shen Yuan gives his life to protect the peace of this small world.

When he returns,

Wen Feier, once so arrogant and domineering, has become a marshal revered by all. Yet his dazzling red hair remains unchanged.

A pampered gong, a pampered gong. Anyone who can't stand that, stay away!
