My Perfect Boyfriend Is Beautiful and Cries Easily, but Why Is He a Monster?

[Rental Apartment + Nonhuman + Tentacles + Younger Man + Tsundere, Sweet on the Outside and Dark Within + Powerful One's Humble Devotion + Doting Husband + Forced Love]

On the train, Qi Muyang is "taking" his coming-of-age gift when an unexpected young man ruins everything.

He wants to bite through the young man's neck.

But later...

Biting through his neck turns into leaving love bites.

He can't stop clinging to the young man, kissing, hugging, pressing close, and rubbing against him.

Just as Qi Muyang is thinking of starting a pure, innocent romance, the young man discovers his monstrous identity.

He runs away.

Qi Muyang can only explain in desperation:

[Baby, I'm a good monster. I don't eat people (*╹▽╹*) I'm very well-behaved.]

[I have savings, a car, and a house. I can give you all the security a human needs.]

[Send me your address. I'll come pick you up and take you home, baby Ծ‸Ծ.]

Thousands of messages sink without a trace, then the red exclamation mark appears.

Qi Muyang completely loses it!

[Ah, damn it, do you want to die!!]

[Are you really not afraid I'll destroy you?]
