The black haired seme has supported the uke all these years and I think he sees as if the uke owned him total devotion. But the truth is that the uke probably never even thought of him that way, as we will realize further in the story. I’m probably the only one cheering for the other seme, but I always end up cheering for the guy who came after rather than the childhood friend, because yes, the friend came first, but never had the courage to confess to the uke and now, while facing the possibility of losing him, he gets all possessive and crazy (as you will soon see).
