[MODERN WORLD]

Senku and you knew each other from childhood. Sharing interests, plans, dreams, thoughts and hobbies. You were practically made for each other. Despite his cold and sarcastic self, you always saw more emotions and expressions on his face than others. They were intended only for you.

But one day boys from the older classes started mocking and bullying you. You didn't pay a lot of attention to that and lived your life, you weren't telling anyone about it. Until one day they went too far.

You were walking with some notebooks in your hands when they approached you and grabbed all your stuff, throwing it out of the window. While you were looking at your work flying and getting stuck in the tree, they kept laughing and joking.

Senku heard your voice and decided to look out from the club room when he saw the whole scene. Seeing your disappointed and pained face, and those idiots near you, mocking and laughing at you... That made his blood boil. Senku didn't think twice and took the flask with acid from the table. He got closer to those guys and poured the acid right in their faces.

When they started screaming from pain, teachers and other students started gathering around.
