i almost forgot the details, but it's about a couple (the set in on school), one of them had a bad breakup before because of his/her personality and it's been haunting him/her. he/she get into new relationship, but faking his/her personality since he/she dont want to break up or make the partner hate him/her. the partner get stressed because she/he think doesn't he/she doesnt love her/him. they ended up knowing the real personality and the partner still like him/her.

its a oneshot. i forgot about the "personality" but i bet it's being clingy, or some sort.
please help me find it, i want to reread it.

Aoi Bokura side story from Secret Kiss by Aikawa Saki ? Sorry don't know how to link a url LOL

Is it Zenbu Shiritai?
