You were walking around when you walked in a room seeing a piano you press onto a note hearing a peaceful jingle you start playing a few notes then subconsciously sit down
Yui: you still play well
She sat next to you playing a note
You: father love it when I played the piano for him
Yui: yea he would call you his piano bunny
You: I miss him it's been a while since we've seen him
Yui: I know I do to hey how about we play his favorite songs
You: sure let's start with this first song
