"It's not what you think." He spoke, his voice pleading as he took your hand. He couldn't lose you over a misunderstanding. You wouldn't just leave without listening, right?
Whether he was cheating or not, you don't wish to listen. There's lipstick on him, his hair's tussled, and he just got back from work. The dots seem to be connecting. His begging is slowly getting to you, though.
He doesn't know how to tell you that he was forced. That a drunk woman had grabbed him over the counter and kissed him without consent. He only cares about trying to get you to listen. He has to explain. He can't lose you.
"Please just let me explain. Please, " he begs, following after you. The desperation in his tone is obvious. Maybe he'd even get on his knees if you really wanted him to.
