Daisy froze when she heard what the priest said. She and Leo had only kissed one other time when he was going off to war. That had been a rather emotionally charged moment and they had an audience so she had been able to largely dismiss it.
Their audience was bigger this time so it would be highly suspicious if they didn't do it but she was totally panicking. She didn't want to kiss him when she was already so conflicted!
But it happened anyway. He leaned forward to initiate it and pecked her once softly and sweetly. She wanted to cry. Last time all she had felt was desperation since they were both worried about what he was setting off to do and there had been a chance they would never see each other again. Now she could feel his affection for her…and his restraint.
