I feel the seme has his set of guidelines for this relationship, but it doesn't work for him because he cares more than he knows. He doesn't want entanglements, but he keeps coming back to the uke at critical times and entangling himself.:)
I think it's because he doesn't want to get emotionally involved. Uke haven't move on yet and they might end up overstepping boundaries that could result to false feelings (y'know, usual issues). But he came back because he can't leave the uke. So that's him, overstepping his boundaries. And kinda making him (seme) and uke a little defenseless.
Wait wait im confused!!! Didnt he just reject the uke's request and tell him to go home??? And as the uke was about to leave, the seme suddenly COMES BACK??? AND SUDDENLY WANTS SEX??? HUHHHH?? LIKE WHY DID HE COME BACK???
Why am I so dumb
