12th of April, 15 years ago. In the city maternity two babies were born. They were put together in the nursery room. Their cradles were right beside each other. Sachiko pees on her diaper and cries and Tarou gets upset because he can’t sleep. A young nurse changes Sachiko’s diaper. When the nurse is holding Sachiko, there is an emergency and she puts her down on Tarou’s cradle by mistake. They have their first fight. When Sachiko finally falls asleep, Tarou pees his on diaper and starts crying. Now, Sachiko can’t sleep. They fight again but they end up peacefully sleeping together. This is the story of Sachiko’s and Tarou’s very first night. Their second meeting wasn’t that good either.
