It's been so long since I've read it so I honestly just remember the ending but I know that it was ABO and one guy was a beta and the other was an omega. They end up living together and I remember there was a time skip scene where the beta comes home and the omega compliments the beta's long hair? Or how he liked how long it had gotten? I also remember something about a bath when the beta comes home from work. The time skip part was at the end of the manga.
You can't leave me with a cliffhanger like this!!! :(
