Hi, looking for name of a manga where main character falls for popular flat chested tsundere type girl. Gets his chance when he happens to come across an event where she's turned down by popular guy for wearing falsies (though it later turns out that the real reason he'd turned her down was that his thing got caught in his zipper and he was in too much pain to do anything).Comedy type manga and pretty sure it's completed. 6n142z

This ring a bell for anyone?
Thanks.

i don't know of a borderline-h manga where that happens, but Yanagida-kun to Mizuno-san has all you ask for, but it is a hentai

Yup that was it. Thanks! I didn't it as hentai though - probably why I couldn't find it. 😀
Cheers!
