If You Remove the Kind Protagonist’s Mask

In order to survive, I robbed the male lead by covering his lips with my lips. That’s why he became my life partner.
But in the original, the ‘gentle’ male lead is all fake!
“If you kill me, maybe this relationship will be free”
“You won’t be able to do it. We’ll both die at the same time.”
We were bound together by a firm destiny. Share the wound, share the pain, share life and death. Furthermore, is contact for the sake of symbiosis necessary?
He did not hesitate to have his mask discovered, but was also cruel to me.
Overworked, unreasonable demands…
Why can’t I be with other boys?
“I know it! ‘How to release friendships’”
Now that my life is safe, I just need to try to escape again…
“I have no intention of letting go.”
“…What?”
“Like what I’m curious about”
His gaze slowly fell to my lips as he hugged me
“I also wonder how much our pain will be shared.”
