So what I got from that is that the main two were using the same gay finder dating app and found each other, they were friends for a little bit and then they met again after (?) the military service and then they got together gradually. But I’m guessing that their relationship is fizzling out on the uke’s side for some unknown reason and the seme is trying to understand why, with perhaps a suspicion starting towards the professor (?)

I don't understand, are they already a couple?? ┑( ̄Д  ̄)┍
