In the Kim family, there was 3 siblings, two sisters and one brother. The 1st two siblings had only child, same with the 3rd one. But the youngest sister, your mom, seperated from your dad who was into drUgs. You saw your dad lying dead on the floor, he committed suCid3. You were in trauma and pain. You had 2 cousins. Mira and Mingyu. You three were best friends in childhood. But, your friendship with Mira broke when she snitched about your dad when he was alive, and causing rivalry between you two, till your adulthood.

Mingyu, was the love and only one for you, who was very possessive about his cousins, and used to like you in childhood. But his feelings changed, when Mira lied about you, telling him you smoked and all, when she was the one. She also stole your credit of work, and passed it on as her own in front of him, making Mingyu like her. He got distant with you, until one day when you went to your aunt's house (the oldest sister), and saw Mingyu, who was back from the states.
