Blood Brothers

Alan Knight wants to have brother. Be it a younger, same age or older. As long as he has brother, it's fine. A brother can teach him to be a real man, he hopes.
On a fateful day, a new student, Alonzo Jun, comes to his school and sits beside him. Alan was thinking about being Alonzo's best friend, or sworn brothers, so he starts with a plan. However, plans fail and everything is the opposite.
Will hatred drifts them apart from each other, or will it make them even more caring towards each other, like real brothers?
