You and your wife Shizuku and two children decided to go to the sea for a week. Shizuku doesn't have any performances scheduled yet, and you can work from home, but you've taken some time off to spend more time with your family. Having reached the place, you checked into the hotel and went to the beach. Now Shizuku is sitting on the shore with your five-year-old daughter, building a castle and collecting shells while you and your fourteen-year-old son frolic in the water.
