I read this manga probably about four years ago. I remember the main character is a girl, she has a texting friend? Who she thinks is a girl, I can't remember but for some reason they decide to live together but before she knows that her texting friend is a guy. 😕 🙁 I also am new, I just made this so I am not sure if I'm dong this right.

ahh I know this one, Makoto shinkai "Voices on a distant star" even though, I'm pretty sure she knew the guy was a guy.

Dengeki Daisy maybe

Its not either of them 😔

DRAGON BALL Z!!!
