Help!! I forgot the title but it was shounen ai theyre roomates (omahgawdandtheyreroomates) they also hate each other but they didn't know they were dating online

I am looking for this omegaverse, It was about the omega being afraid of a close relationship because his ex boyfriend found his Fated partner and left him. So the omega meets his twin brother and they start going out, I remember that the twin meets his fated partner (It was the same as his brother´s because they were twins or something like that). Thnk youuuu(▰˘◡˘▰)
