What Should I Do If My Boyfriend Is a Beast That Feeds on Evil? Hunt Down Criminals and Feed Him

To stay alive, Zhu Sui'an signed a feeding contract with a Sin-Eater.

This handsome contract boyfriend, whom she got for free, is incredibly capable, but hard to keep fed.

He's from another planet and survives by consuming the evil thoughts in human brains.

Zhu Sui'an, a journalist who reports on the legal system, is forced to moonlight as a detective. Relying on the Sin-Eater's keen sense of smell, she contends with criminals and races against the police, working herself ragged to feed this picky eater of a kept man.

But what is she supposed to do about the vengeful urge to mete out justice herself and the cruel thoughts with nowhere to go, all festering in her own mind?

Her Sin-Eater boyfriend keeps drooling over her, craving her brain!

Zhu Sui'an: You sucked a serial killer until he got brain atrophy, and you've replenished enough energy to return to your home planet, right? Our contract is fulfilled. Off you go, and don't come back!

Lu Ye: There's only one way I'll leave: you come with me.

Zhu Sui'an: Stay!
