Yesh! A lemon! Thank you for uploading it. The "H" scene of S&S made me laugh, grin, and blush, my friends thought I was turning weird so they had to make plenty of space to avoid misinterpretation of perversion from others.
There are also some parts that you need to beta, but they are just minor mistakes.
I'm just wondering who's the background character(Yuuno's room-mate) that you had mentioned in the story?
