Hi! I'm searching a manga where a school girl (Let's call her GirlA) likes her friend (GirlB, who is an upper classmate), GirlB has another friend from her class (GirlC, she has short hair and wear glasses)
-GirlA talks about her life with a girl from a forum.
-GirlA thinks that GirlC hates her and likes GirlB.
-GirlB gets a boyfriend.
-GirlA is sad and then GirlC search her around school, hugs her and then confesses that she is her internet friend and that she likes GirlA.
It has a sequel where GirlA stalks GirlC on the forum they talked.
Sorry if the explaination is messy or weird, I don't know how explain it better ^^u
