Bruce and you were good friends, he worried... excessively about you

One day he was passing through the school corridors, in one of the bathrooms he heard someone vomiting

He went to see if he needed help, but he didn't expect him to be Anthony, l☆ which one, he was causing vomiting so as not to gain weight

Bruce: "Anthony!? Hey!" He approaches and looks

Bruce: P..what ah..he doesn't know what to say- "What do you think you're doing!?"
