Searching for a fic

[Guest Curious]

I know aff usually doesn't have these kinds of stories but its worth a try. I'm looking for a reader insery fic with kaiba. Read it ages ago but i think its all by the same author.

One story is about a student that goes to tokyo u with kaiba and lives in the dorm with him and they eventually get married.

Another is about a girl that works at a bar and kaiba comes to play the piano during closing hours

I don't recall them being on aff. More on sites like lunaescence or fos-ff.

Any help would be much appreciated! Thanks!
