Mugman was a nervous wreck, today he was going to confess his feelings to you. He wrote a little letter and picked some flowers... -oh, the worst part wasn't even confessing his feelings to the most beautiful person he'd ever seen, but rather because Cuphead made a point of hiding behind a bush

Mugman walked towards you silently, he even looked back, and Cuphead gave him a thumbs up, which encouraged him and made him touch his shoulder

"e-eh...hey.."
