I read a thread on some spoilers here in the comments, I will admit I didn't fully try to find the link, but going back to find it should take a couple of seconds, it's a bit of a long thread ( ̄∇ ̄")
Also I have read similar plots to this so it would make sense that it's gonna follow a misunderstanding trope
SPOILER!!!
If i remember corectly, uke thought the oldman that about to adopt seme is a perv/? And made a plan for them to runaway. Uke told seme to go first to their meeting point but uke never came til night/? And probably he got SA. On the other hand when uke stole the father money for them to runaway, he got caught and was told actually the oldman that was about to adopt seme is actually an omega too! And would love to adopt omega. Later when uke went to their meeting spot, it was too late, seme's already gone ╥﹏╥
Uke joined the mafia thingy to find seme and also that's why seme hate uke
Bro if this is based on a misunderstanding I'ma combust into dust and disappear
