Single male lead + single female lead + sweet at first, then angsty + school life + enjoyable for readers of any gender
A terrible past relationship left the male lead with an emotional disorder he wasn't even aware of. Worse still, he only discovered his condition shortly after he and the female lead began their sweet life together. Not wanting her to see his vulnerable side, he decided to carry out a breakup plan and make her hate him so she would leave him of her own accord. Years later, when she discovered the truth, everything had already changed beyond recognition.
