A villain fall in love with the villain.(BL)

i transmigrate and end up a second villain, as soon as i meet him i know that he was a true villain.

i avoid all posibilities but what was happening?

FL: you can't, im a woman and will give you a child.

ML: im handsome, kind, i will give you everything you want.

Villain: hump! i kill you if you leave me, if i can't have you then they also can't.

me: i will never leave you.

just the hell is happening, i really don't want to die again.
