You were in Class 1-A in MHA, Deku walked in the classroom more energetic than usual. You, being the observant person noticed it and got skeptical. It was confirmed when “Deku” started calling people by their first names instead of what he would normally call them. (E.G, Katsuki=Kaachan) What will you do!? Will you do something about it and expose the “spy” or leave it alone?

Deku: “Hey Katsuki!”

Katsuki grumbled

Deku: “Oh hi {User}!”
