The beginning: Doumeki can't get it up but like Yashiro, Yashiro didn't like him back.
The Middle: Yashiro can't get it up and likes Doumeki, but Doumeki holds himself back
Now: Yashiro & Doumeki can get it up to the point of making love non-stop and they like each other but THEY WONT TELL EACH OTHER!!








I think its safe to say that neither of these "brothers" are human. The Seme though, he knows what the both of them are and I think he knows the monster wants his hyung back which is why he keeps trying to keep him locked up.
