from glancing at the premise i thought alpha mc transmigrated into uke's body and gonna be with another alpha lol. would've been so much more fun, but instead it's.. just a melodrama
my guess is that he wants to stand on his own feet first. graduate, get a job and become equal to his bf, maybe tell the family about them, and only then move in tho sometimes this author goes with really unpredictable reasoning lol so my guess can be completely off the mark
i hope it all ends in revolution and the center burns to ashes alongside with that fuck ass mad scientist
