My Enemy Is My First Love

I have a love-hate relationship with my first love, Ji Yura, who is the elder of twin sisters and the very same person who bullied me and cruelly rejected my innocent feelings. Then, my first love changed to Ji Yuri, the younger twin of Ji Yura, who comforted me when I got bullied. However, when I thought I put those painful memories behind me when I started university, Ji Yura reappeared in front of me!
