A day when you're sick, a day when you have troublesome daily duties, a day when you have a regular test... On days when she doesn't want to go to school, I get called.A clone of a girl named Aikawa Nao, a convenient scapegoat, that's me. Her appearance is exactly the same, but her personality is a little different.A replica whose mission is to work for the original, who can't go out freely, can't even make plans for tomorrow."I should have been, but I ended up falling in love."In order for him to recognize me, I put my hair halfway up.I skipped school and secretly went on a private excursion. And we promised to meet tomorrow, the day after tomorrow, and beyond.My name and body were all borrowed, and I should have been empty--this love is only mine.A very pure and slightly mysterious "first" youth love story that takes place in a seaside town.
