I have an off feeling from the older brother, as soon as he heard his brother knows the little guy, Ideum... I reckon there's a rivalry between brothers and the older one is used to attention and doesn't like when it's not on him but on his lil'bro, so I guess he will try to win Ideum over just for attention because Jaeyi is interested in him and will loose interest in Ifeum the moment Jaeyi isn't caring about Ideum
