I'll Give You the Most Rotten One

Synopsis

After 10 years together, my boyfriend cheated on me with another woman. Devastated, I decided to get revenge. I wanted to hurt him as much as he hurt me. Thus, I carefully planned the perfect way to get back at him. Our relationship was already over, but this was the final nail in the coffin. Now, we're both left wondering if we'll ever be able to love again. I don't know if I can forgive him, but I know that I can't live like this. I need to find a way to move on, even if it means hurting him in the process. This is wrong, but I can't help myself. Consumed with anger, I just have to make him feel the same way. Even if this isn't the answer, it's all I can do. I just want to feel loved again, to feel happy. Is that too much to ask? (Source: Ezmanga, edited)
