Hwang Hyunjin.

You knew very well that Hyunjin worked out a lot, and proof of that were his muscular arms, wide and capable of lifting you without a problem. You had a very small waist, so much so that Hyunjin could wrap it around him with just one of his big, long arms. One day, while they were riding the bus, it was full, so they both had to stand, and so that you wouldn't fall, he wrapped your waist around his arm, holding you up.

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