14-sai no Koi [Manga]

A story about two fourteen-year olds. Because of their outward appearances and their academic achievements, they are thought of as being extremely mature by their peers. Consequently, they feel the pressure of having to live up to this image. They are both smart, very together and they are in love. But, as grown-up as they act, they are still just fourteen, and their feelings for each other are captured with tenderness and lack of nostalgia, but very cutely.
