Krystal (soojung ) was a normal kid that go through a tough times at her curret school she transferred in. She was bullied by Myungsoo all the time literally everyday. As she has to change classes sometimes, she had to sit with minhyuk the cold person minhyuk is not really a cold person, it's just his present year change from past usable the change is suppose to be bad to good but for him is the opposite so he trust no one even his mother-in-law and Myungsoo his brother. Krystal had a secret crush on minhyuk but she could not find a way to melt his cold heart will she? Or will she fall in love with Myungsoo?
