Spoiler
in the earlier chapters it is said that they met when they were younger and our omega is his first love
Well that's true i did read that page. However he was a beta when they saw each other having that blond bitch carry his fiance's baby(ooh my blood boiled everytime.) and transcended to omega after he died. But what curious me is the last word he says, maybe you are right it me something to thier childhood phase.
Most omegaverse that I read is that usually they won't know their second gender until a certain age so maybe when they met when they were children they didn't know what their second gender would be. They probably didn't know if they were gonna be omega, beta, or alpha. But who knows maybe I missed a chapter or what .
Some people are thinking he drove the blonde omega to the black haired guy so that MC would become disillusioned and leave him. He probably didn't think MC would kill himself.
True, well he owns a black market maybe for business and that's something Author-nim might add if he/she do have some spare time for flashback. but lets not dwell on the past lets continue having Master and slave or dog Hahahah full meal course ε=ε=(ノ≧∇≦)ノ
I don't usually like smut but they I have to admit I loved the dynamic
Did the red hair guys came back to past as well as the MC ? Or did he have some vision (⊙…⊙ )
