The minute the door closed, the smile dropped of his face as a darker look took over. It was a lie to say he wasn't swayed by the mood they had going. She had teased him a couple times today and as revenge decided to play around about the shower. His intention was just to keep it light but make her flustered. All of which he did, yet....the more he spoke the more sincere his offer was.
It started off as a joke but at the end it was an open offer. He wasn't sure if he should be upset or happy she rejected the offer to shower together. Upset at losing the chance to have her in his arms again, happy that she had stopped him before things had gone too far.
