Jae grew up taking care of his younger brother Shinjiro . he love his little brother more than anything in the world (of course his wife and kids too... but yeah ) and would always spoil him and do everything for him.....
when they were younger , jae would hug shinjiro to sleep when it's raining heavily. Even though Matthew took over "the job" of doing it.. Jae seems to got his "job" back.. ;3;
your typical brother who is crazily protective over their younger siblings... and Shinjiro looks like a girl since young so he been always making him wear cute dresses and tying his hair into twin tails... oh Jae
but u can see..sometimes his "love" gets outta hand... *laughs*
but nevertheless Shinjiro love his older brother alot too.
