I think your taking the story a little to harshly
I think satoshi has a personality that makes it impossible for him to refuse people. He hates what those people do to him but he is unable to hurt or push them away when they force themselves on him. That's why he has a owner and not a boyfriend, so someone else can push the others away for him.
As for yuuji it was obvious he was falling In love with kyouya but then got scared and ran away
There is a side story about these two it shows them in the future it only has 2 chapters right now though (=・ω・=)
Well if the kyouya story is not finished here im looking forward to it (≧∀≦) But still no matter what i hate satoshi (￣ε(#￣)Σ
Lol
Satoshi is little useless, all he do is making Izumi worried and need Izumi to chase after him.
His soooo gullible in a tragic and dangerous way (￣ε(#￣)Σ
I really hate satoshi and every story about him .God he's so loose just let the passing dog in the park or something rape you too then it's complet . what a hack(╯°Д °)╯╧╧
And feel so bad for poor kyouya ╥﹏╥
Yuuji totally trashed him and tossed him away
（/TДT)/ why poor kid
