Oo-maji, Dead Serious, 大本気
Souhei, an honors student since he was little, is at present an elite dentist. Jin, who was a bad kid when he was little, is now a bad boy construction worker. Living in the same neighborhood, the two happen to meet in a strange setting. Every single thing about them is too different, and they shouldn’t be able to understand each other, but somehow they formed a connection! He has a feeling that what should have been a painful experience is going to feel good…?! The brute of a young man will have his training etched into his body!
