The Evil God's Offspring Tries Hard to Pass as Human

Romance and everyday life + Cthulhu + multiple female leads + eerie happenings + very sweet, no angst

A notice titled "A Guide to Human Survival" is posted in Ye Suwu's home:

1. Appearance and posture matter. Be sure to look in the mirror before going out!

2. Ordinary humans have at most two eyes, not hundreds.

3. You must not eat the plate along with your meal!

Warning: Humans are extremely dangerous! Under no circumstances should you reveal your true identity!

This is a world once torn apart by corruption.

Powerful human ability users and martial artists regularly hunt down the eerie beings.

As a severely wounded young evil god, Ye Suwu thought he would have to live forever in fear of humans. Then the System arrived.

As long as he acted like a human and did things befitting his human identity, he could heal his wounds and regain his strength.

Just as he was racking his brains over how to "act human," the System suddenly issued a new mission:

[As a healthy human male, you should have a sweet romance with a woman. That's what it means to be well-rounded.]

But the girls he met all seemed a little... unusual:

A gentle, domestic tentacle monster auntie with the ability to shapeshift;

An energetic, loyal stray girl with an immortal body and terrifying strength;

A gorgeous, lovesick childhood friend and school beauty who just happens to like silently snapping people's necks with her shadow;

Ye Suwu was at his wit's end: (╯°□°)╯︵ ┻━┻

"I'm doomed! It seems all the girls I've met aren't human!"

Then, on second thought, he covered his mouth.

"...Luckily, neither am I."
