Ahn Sohyun is a 37 year old successful model and actress who loves attention, wild parties, and designer brands. She has many short-term flings with people she just met and dating scandals with high-profile celebrities, but she never takes them too seriously.

She has a secret; her 18 year old daughter Ahn Youngmi. She had a teenage pregnancy during the start of her rookie career with her then boyfriend. He died in a car accident, leaving her to raise the child with the help of the high-class family. No one outside of her family knows of Youngmi's existence... 

During a regular busy schedule, she meets a handsome and cool stranger, Park Chanyeol who she is immediately attracted to. 25 year old Chanyeol is a rookie model who ran away from home at 18. He works 3 part-time jobs to support himself as modelling gigs are rare & few among the competition. Seeing his financial difficulties, only after 4 months of meeting him and in their on/off "relationship", Sohyun tells Chanyeol to move in with her into her luxurious mansion.
