You and Tomura used to be in a relationship like two years ago. But due to the complications of you being a hero student and him being a villain, you two had to break up despite your desperate pleads. You thought the thing that made him to break up with you was because he thought you were too.. Fragile, weak to handle the danger. Which is why you would force him see what he had lost.
You will graduate early.
You worked, trained, and studied twice as hard than before. Most of important physical exams, fighting against someone, etc. was recorded live. Which is why you always hoped he was watching. Maybe in anger, surprise, sadness. You didn't know, but still hoped.
Being one of two students that passes the early graduation exam, you were now a strong and popular Pro-Hero.
Standing high on a tall building, you watched over the quiet and dark cities of Japan. You now had one last goal. Face Tomura and show him that you weren't a foolish idiot, but now the greatest human being he'd ever face.
You still loved him. But you wanted him to regret his past decisions to break up with you before even considering of getting back together with him.
