Seo Rin tries really hard to get her mum's acknowledgement. Thus, by entering an arranged marriage is her only way out.    Jongin has a girlfriend already but he gradually fell for Seo Rin. Ironically, Seo Rin is just emotionless, just like a porcelain doll, fragile yet empty. Reciprocating feelings is not her style.   Sehun at one point in time convinced Seo Rin. To run away.      ---------------------------------------------------------------
