thought it was really sweet, but sadly too short

thought it was really sweet, but sadly too short…
the character of the brother was just shown on the superficially:
why he hit his own brother and the reasons ~> because of fear? out of protection? <~
dont kid me! you dont hit people for protection ! not in that case, stupid big brother !
i am not satisfied with that ending at all ! or with that half-hearted "sorry" in the ending…
