I think it's just an illustration by Umezawa Hana.

Actually never mind, i think it's a couple from this one:

Thank you :)

Also I just thought of this other one but I can't remember the name of it T_T I think it was about a couple of friends from college who still hung out together but one of them secretly liked the other the entire time and so they ended up together.
I am probably annoying you so thank you for the help

Oh no it's not annoying at all ^^. That's not a lot to go by, but it reminds me of this one:

Lol I'm actually reading that one. That's what made me think of it.
