No and no. ML is not adopted not a stepson, the father didn't wronged the father. ml father was falsely accused of treason, mc couldn't help his best friend then he found his son and rised him, hiding his origin. Mc thought ML was his father's son from a lover, but even when mc knew the true, he still bully him.
Anyway mc and ml are obsesed with each other but for diffent reasons.

Are they blood related in anyway???....is the top actually the son of the father of the bottom ???...dont wanna start with some step bro stuff
