he was aiming for the armpit fold. There is a big artery there and you can literally die in seconds bc of blood loss, if somebody stabs you in the "right" place. You should point the finger for being stupid at you lol Also, stabbing the thigh would bring nothing. You always need to aim at places with big arteries, since the point of stabbing is fatal blood loss.
Armpit fold is technically much harder to aim precisely when blondie is practically already bending his body due to just being stabbed, and gyuhwool can easily dodge with his hand since armpit is much higher, hence takes longer to aim the knife..
Whaddayamean thigh wud bring nothing?? Never heard of femoralis artery? One of the biggest artery in ur body! Very easy to point from blondie's lower point...U know a world wide champion in iceskating died not long after being stabbed...damn i point the stupid finger for you then

Huh?? For someone who can use a knife and on the peak of killing rage this blondie sure is soooo smart aiming for a shoulder instead of abs, thigh, neck or heart ┑( ̄Д  ̄)┍
