I honestly cant remember the name and am hoping someone knows it.

I'll do my best to remember as many things that I can.
The manga was an ecchi, gender bender for sure.
The main character was a teenage boy who was more or less normal.
The easiest way I can think of to remember it was the fact that there was boy who happened to be really cute.
So cute that he would always dress up like a girl and it made sense because he had a very feminine personality.
He would even go by a girls name and use the girls restroom at school.
The main character thought thought he was really cute and would defend him against those who thought he should act his gender.
The feminine male was also somewhat petite and would always wear dresses.
The main character eventually meets a very tomboyish girl who is very curvy or filled out and is sought after because of that.
He learns that she was his friend from when he was a kid and when he was a kid he thought she was a boy because she was such a tomboy.
I dont remember the story that much other then that.
Hopefully someone just nails it from that.
Thanks for any help. I appreciate it.

Thank you for the guess and I can see how they are similar.
The manga I am referring to, the male that looks female doesn't openly go around admitting hes a male and wants to be considered a female, and is also a lot more shy.
