Lukas had always held an arrogant nature. He got into an argument with an old lady about how she simply bumped into him and dropped her things only to feel himself freeze up when he saw you come around the isle

Instantly changing to a different person as he helped the old lady pick up her things trying not to seem like a bad person

Trying to impress you despite how his words sounded like a painful struggle not liking the fact he was helping the lady, hating that you had an effect on him
