IMO it was amazing how the story wasn't made to be overly sexual and the whole story is them literally just starting their relationship, expecting them to jump straight into fucking screams that you don't know much about bdsm outside sex. A bdsm story being just wholesome is a need sometimes too
and also the seme was adorable fym
Actually I don't remember it at all so you might be right ╮(￣▽￣)╭ and I really agree your idea about stories with bdsm(≧∀≦) if you didn't read it, I could recommend this story

It is one of my favorites, if you are interested in psychological and philosophical aspects of bdsm. I hope you will enjoy reading itヾ(❀╹◡╹)ﾉ~
Seme is a little bit annoying in some parts and it is wasted potential of good smut scenes so it is disappointing yet they are cute
