If you corrupt the heroine's first love

I won't be posting the novel cover (but hope you enjoy it)

I don't own or have written anything in the book I'm just translating it...

A test subject mixed with Medusa.
A villain who destroys the world.
This is the identity of the character I reincarnated.

My hope is that the original story will not go wrong and that we, the evil of the world, will be completely destroyed.
The only way to avoid interfering with the original story was to live in hiding, so I lived in silence for several years. But why?

"Are you going to leave me alive and abandon me now?"

Was it because she saved the first love of the heroine, who should have died?

"I betrayed God."

He used to be a holy knight who served the gods blindly, but not now.

"For you."

Kakapage split the chs into parts (there are 144 chs in total but I'll try to post 1whole ch of the book in 2 parts)

Just one human who has fallen.

"My life belongs to you."

His sacred eyes were glistening with immoral desire.

"Forever."

To the point where I can't resist, a deep desire.
