There were a guy and a girl, if im not mistaken they're senior and junior in a college. the guy can see if someone is in love like he can see sparkles around them, but somehow the girl didnt sparkles even tho she likes him. Then he got to know a feminine girl and they started to exchange diaries??

I read it a long time ago, probably there are mistakes in my description, but it would be great if someone can help!

Koi wa Hikari??

yes!! thank you very much!!
