Well I'm guessing (hopefully) at some point Momo will find a love interest and it will be more like a relation of older sister - younger brother between them or else I feel like Momo is gonna be some tragic character for the rest of this manga.
Oh my, not the classic "I told you I was going to your recital but ended up having a date with someone else that just seems to be at the same date of your recital :p", now I'm interested in how she's going to keep both guys.
