After Edmond's speech, Kevin became silent and unable to make a rebuttal. He was pondering on Edmond's words, he was right. He needs to man up. Right now, he was at a low point of his life. Things were not going well with work and now, his not so blossoming love life. He hated Edmond so much for coming back and stealing Amy away from him but in truth, he hated himself for having no courage to express his feelings and missed that opportunity of having a romantic relationship with Amy.
Feeling defeated and losing the competition, he started to make sobbing sounds. Everything around him seems to crumble and fall apart. He had never felt this way to any girl before. To others, he was just extending a hand. Being a brother that cares but in the case of Amy, he knew that he was in love with her. It was just that she was never over Edmond even when he left. He remained waiting until she was ready to receive him but instead Edmond came back and so as her feelings for him.
