Kibum and Jinki had been living together for five years and they eventually agreed to put their relationship into a high level, the commitment of marriage. They had chosen the right date, booked a wedding party hall, fit up the outfit, made the list of the people they would like to invite, and they were even looking for a new house already. Kibum thought he was going to be the happiest husband ever when Jinki proposed that night and thought that nothing could make them apart after that. But when someone from the orphanage came to their apartment, with a five years old little girl holding her hand, claiming that she had the certificate letter from the mother of the child, written that Jinki was her biological father, Kibum knew this was going to ruin everything.
