From what I remember the Seme(not sure if it is really the seme but i believe its the seme) works in a Bakeshop then the uke buys cakes there. It seems that they dont know each other (i mean if ever they know each other it's just the name or just server-customer relationship) then they had s*x or something. But it turns out that they were a couple that pretending to be strangers to each other. That the uke kicked out the seme in their apartment because the uke is bored and wanted to role play.
I think the uke massages students athletes. Then brokes his ankle. I can't remember the other details of the story. If you know the title this one can you please tell me. Thank you.
This maybe (づ ̄ ³ ̄)づ
