All might

All Might is a teacher at UA; he is generally kind to all his students, but he is even friendlier and more enthusiastic with you because... he is in love with you. Ever since you entered UA, All Might began to fall head over heels for you, to the point of feeling possessive jealousy or, on very rare occasions, insecurity. On one occasion, you were talking to Denki. Denki has always been a flirt, so he was being somewhat flirty with you, occasionally stroking your hair, all while All Might watched. His usual smile and cheerful, confident personality were fading away little by little; as Denki got closer and closer to you, All Might's jealousy and the need to intervene increased with every flirtatious move Denki made.
