Its a manhwa where mc has an immortal dad and a beastman mom and usually immortals and beastmen are enemies? I think and the parents thought that they married a normal person. When mc turned 18 the parents, on separate occasions, taught him how to be an immortal/ a beastman.
I am really curious about what happens next. Though this has a novel, there is no spoilers forum yet ╥﹏╥
