ok so for those who didnt watch the drama:

Sua - Ji Sunwoo (got cheated on, RICH)
Jiu - Sul Myungsook (sunwoo& #39;s colleague who& #39;s annoying as shit, eyeliner on point)
Gahyeon - Yeo Dakyung (fell in love with Tae Oh and had an affair with him, deserve a better partner)

-cont-

Siyeon - Tae Oh (white shirt, cheated on Sunwoo, lived off Sunwoo& #39;s money)
- Dakyung& #39;s mother (black shirt, dakyung& #39;s no. 1 supporter, nasal voice)
- Dakyung& #39;s father (red polo(?), wants only the best for his daughter, is actly the most sane character in my opinion)
