What Monica didn't know, was that Arnold was here with his wife.
She had thought he came alone and she hoped to make him feel uncomfortable in various ways. She turned to James and planted a kiss on his lips. It got a bit more intense when James assisted her head with his hands, devouring her lips deeply.
"Ahem!" Levi exclaimed. And they understand fully what he meant but still, they ignored him till they were satisfied with their kiss.
Monica turned to Arnold so she could see his reaction but he maintained a straight face. She's known Arnold for so many years and she understood this looks quite well. Arnold wasn't disturbed at all. About her presence or the kiss. Matter of fact, he had that unperturbed looks on him.
James grabbed her thin waist which she wrapped in a corsette belt that matched her peach gown perfectly.
"Well, what are we celebrating?." Monica asked. Breaking the silence.
