나의 원수 첫사랑

I have a love-hate relationship with my first love, Ji Yura, who is the elder of twin sisters and the very same person that 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 when I started university, Ji Yura reappeared in front of me! (Source: Lezhin, translated)
