im so conflicted that Lee Hansoo is the actual brother of Yoohan BUT hear me out. Yoohan indirectly mentioned that his brother was in 9th grade when he died i.e., 15/16 yo. (5 yrs time skip) Lee Hansoo (actor) is 20yo. Their surnames are the same too. But Yoohan saw his brother dead and probably(???) had a funeral and he would've recognised his brother so forget this.
