Tanaka-kun is Always Listless(2013)

Tanaka-kun wa Itsumo Kedaruge

A sigh, chin on one hand, and those tired eyes... That’s Tanaka-kun, perpetually listless as he is. He and a quiet giant, Ohta-kun, who can’t seem to turn a blind eye to Tanaka-kun, come together in this slow, leisurely, and obstinately lazy coming-of-age comedy.
