I SAW that the 1st one (Kihyun) has a mole on his nose and the 2nd, the difference is in the personality, 3rd likes to wear shorts at home and I SAW THE 2 OTHER BROTHERS, which is one of them, has a MOLE under his EYE and NOT ON HIS NOSE. I'm assuming the mole under eye guy is another in law and the other guy (probably the 2nd dude)...
Oh god this reminds me of Given on Ugetsu and Aki's relationship T-T bye imma go cry now
I never thought I'd see Michael Jackson featured in a yaoi
