Hwang Hyunjin.

You knew very well that Hyunjin exercised a lot, and the proof was in his muscular arms, broad and capable of lifting you without any problem. You had a very small waist, so small that Hyunjin could wrap it with just one of his large, long arms. One day, while you were on the bus, it was crowded, so you both had to stand, and so that you wouldn't fall, he wrapped your waist in his arm, holding you.

Hyunjin loves to hold your waist in his arm, he always does the same, no matter where or when.
