First of all, this was such a delight! I was surprised when I saw the brand during the first part of the MV! What a collab~

Alright then, so a DIMPLE is considered a commodity and has been said to be used as bait to entangle a gazing lover. A lot of people are attracted to those who have them and their smiles. 

Like dimples, an element that is equally rare is Mercury or quicksilver. Woosung's blood is replaced by this unpredictable toxic metal and could alternatively mean that he has tainted feelings he wants to escape from, but can't. 

The scene that impressed me the most in the MV is when he is holding the fishbowl in the bar. 

In the beginning, the fishbowl was filled with clear water but suddenly turned into solid-form quicksilver, which could mean he is trying to be cold towards the girl to escape the relationship (mercury can only turn solid in -38°C). 

You can see him with traces of the girl on his hands while he puts the fishbowl down and goes towards her in a trance.

Other notable scenes:

• The first scene where he looks forlorn also made quite an impression on me. The fishbowl made me start to question things right off the bat.

• In the end, he still can't escape his feelings for the girl and continues to drown deep in a sea of desire which is shown in the submerged taxi where he and the girl are in.
