It's omegaverse and ML is alpha while uke is omega (but recessive or maybe turn late? Can't remember). ML was in same highschool as MC and used to have a fiance and fought with his fiance because his fiance was in love with another alpha. Then once becoming adult, ML met with MC, they had slept together.
I can't remember much but the latest i read was the fiance meeting with the MC and warning him about ML, how ML is using MC to make him jealous. Then ML found out and decided to harm the fiance's lover (honestly can't remember if the engagement is annulled or not?)

It is either about the esper guide universe or sentinel universe, can't remember much. The uke had regressed back in time and he had decided to become a better person by not forcing the seme to partner with him. He is also trying to stop future bad incidents. I lost my reading list of it and I can't remember the name.
I'm so mad at the commander and Jin. No idea why but something about them just pisses me of. I want to continue reading it but i just feel bad for the mc , with some second hand embarrasment. Can someone spoil me at what chapter the redemption arc for ml begin
Just read other comments that Jin is actually nice. Thank goodness
