Mr. Macho My Classmate

My name is Yuu Bakuryusai, I’m in first year high school and a little more sturdier than normal people, by a little more I mean a lot more. But that hasn't stopped me from chasing after the girl I love, Tsujizono-san. But wait! There is a note on the blackboard saying that she is kidnapped! Wait for me Tsujizono-san! I will save you with my MUSCLES!!! A story about a boy who is self-conscious about having huge guts and huge muscles, until he meets a girl who changes his life.
