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

Naruse Hiroya is an ordinary high school student, but his normal daily life is often ruined by his friend Kokutou Miyabi. Miyabi has an intense personality, and he constantly drags Hiroya and their other friends at school (level-headed Wasshi and Katarun of the vision-obscuring hair) into the most ridiculous situations!(Source: MangaHelpers)
