From puppy-like looks to Harajuku style, the chaotic Boy Next Door Beauty Salon

Taesan and hair designer Lee Han styled the members, showing off their same-age chemistry as the '04 line.

The first customer, Seongho, requested a transformation from a cold, handsome man to a puppy-like appearance.

The sight of Taesan drawing the tails of his eyebrows downward and boldly applying pink eyeshadow while looking at the instructions

It was anxious yet cute.

With the addition of Lee Han's careful touch as he works his hair on the lowest temperature of the curling iron

The twist was that the result turned out to be cat-like.
