Slow Starter (volume 1)

It's a story about two boys, Kiyo and Ino, who go to different schools but take the same train every morning. As time passes by they become aware of each other but never engage in conversation until one day when Kiyo oversleeps in the train and is awoken by Ino. From that point on they begin talking to each other and eventually become good friends...
