wait how do you know what taemin's brother looks like?
from the internet !
lol jk Taesun (his name ) attended Taemin’s Budokkan concerts with his mom and there were a couple of fantaken pics
this one is from few years ago
he got a Private twitter account where he used to publish some personal songs before going private and also a parivate ista ( i dont have a link sorry)
a little info also Taemin’s playlist on spotify displays his bro’s track
