Hey everyone,
There is this one manga series I read a while back that I can't get out of my head. I've been wanting to read it again, but I can't remember the title. Here's what I can remember:

It's set in Seoul, Korea, but is a manga  
The protagonist is a 15-16 year girl who has entered Highschool with her childhood friend. She's got brown hair and he's tall with black hair.  
She's in love with him but he doesn't know that yet,  
She meets an older guy who is the captain of the school baseball team and everyone calls him Captain  
Some other stuff happens, and the two childhood friends meet this model chick  
childhood friend and this model chick start going out  
He asks her who she likes and she lies and says: "The Captain," who in shojou style does overhear her. he later confronts her and calls her a liar. That's the most vivid scene in the series,  
other stuff happens and she ends up with the captain, who happens to be friends with the model chick that her friend is dating.

It's quite a sweet story and I want to read it again but I can't seem to find it. I read the actual series in a library once but can't seem to find it again.

Please someone, I'm begging you all, please help me find it

Is it this one?

It is better to remain silent and be thought as a fool, than to open your mouth and remove all doubt.

No it's not but thank you anyway. The main character is not into acting or in the drama club. I appreciate your help though
