5 Centimeters per Second — Makoto Shinkai

Love can move at the speed of terminal velocity, but as award-winning director Makoto Shinkai reveals in his latest comic, it can only be shared and embraced by those who refuse to see it stop.

Takaki Tohno quickly befriends Akari Shinohara when she transfers to his school. They grow closer to each other due to similar interests and attitudes; for instance, they both prefer to stay inside during recess due to their constitutions. As a result, they form a strong bond.

Upon ending their school year, Akari moves to Tochigi, due to her parents' jobs. The two keep in contact by writing letters, but eventually begin to drift apart.
