People come and people go. You fall in love and fall out of love the next second. Kyungsoo strongly believes in that based from experience. He despises commitments bounding him especially marriage. He thinks it will never work but nevertheless with Kai, a guy he just met, he takes a chance. He falls in love and for the first time believes in the happiness of marriage despite knowing that he shouldn't have done that. Shouldn't have met Kai and believe in his stupid acts. He knew Kai would eventually meet someone new and fall out of love with him. And the impending doom- he wishes for it all to fade just like his life withering away and Kai's love for him slowly dying.
