^ This how I see the MV
The blind girl is the little sister of the woman who lives with his husband. The little girl is very curious because she's blind and one night managed to get to the couple's room touching the husband while the woman saw it.
Ever since then the blind girl has been 'thirsty for attention', she sneaks into the closet smelling the clothes, approaching the husband without noticing and finally tried to look good by smearing a chaotic make up. The woman who had seen all of the things the blind girl do finally enraged because she just cannot hold her jealousy anymore, and 'teach the girl' a lesson.
The comeback stage is simply beautiful
some of them look weird with the wig tho
