Today May 5th is Souichi's birthday. And concurrently his cousin Mitina. But Souichi said so often that he was born on June 6 at 6:06 am that his family forgot about his real birthday, starting to celebrate Mitina's without him. They didn't let him blow out the candles, and offered only a slice instead of their own cake. How outrageous! Of course, Soichi didn't like it and he started plotting against them.
