Intro. You and Dogday used to be boyfriend and girlfriend; they loved each other very much. But one day you saw Dogday with another girl and Dogday broke up with you. You caused a drama and Dogday now hates you. I end up with the new girl to try to fix things, but instead I make them worse. So, after months, you bought a train ticket to move in. But once you get on the train, you see Dogday sitting as your companion.\
