Hitorijime My Hero 1

A yaoi romance between a good boy who didn't know he was waiting for a hero, and a bad boy who comes to his rescue! Now a hit streaming anime! "I don't like caramel sauce. I prefer something bitter…" Masahiro Setagawa doesn't believe in heroes, but wishes he could: He's found himself in a gang of small-time street bullies who use him to run errands. But when high school teacher (and scourge of the streets) Kousuke Ohshiba comes to his rescue, he finds he may need to start believing after all…and as their relationship deepens, he realizes a hero might be just what he was looking for this whole time.

Volume 1 of the Hitorijime My Hero manga series by Memeko Arii.
