I just read you are my world and I can tell it’s toxic but I remember there being a similar manga or manhwa much less toxic with the same premise two childhood friends one alpha and the other turns out omega because of the others pheromone being to strong but they might’ve been separated young because of that.
Sounds similar

Hello I read a BL manhwa that was very similar to Unfair love affair last year it revolved around a love triangle but there was a soulmates red string of fate situation where the MC is fated to be with his crushes brother. I can’t remember the name forgot to save ☹
Is it this one? https://www.mangago.me/read-manga/salvation_spirit/
I hate this so much
