From OneManga:
In class, she's a sort of zoned-out girl, and he's the year one class' most perfect, good-looking guy. But the two of them have a secret, and their extraordinary "love experience" will start now!
Comments:
-Girl who loves to observe the world around her and writes about it. She seems to have a Haruhi-esq personality.
-Guy has a secret that the maiin character finds out
-I really like the personality of the main character, I wouldnt mind if this is turned into a anime someday
-Hopefully this will be released regularly
