Sorry about that

Growing up below the poverty line, a 13-year-old Senja and her single mother move to a new city in hopes to start over. Senja starts seventh grade at a new school and during the first day Senja gets to know Iina and her friends Miisa and Jenna, but is so ashamed of her background that she lies that she is rich and lives in a big house in a wealthy area. Day by day the friendship between Senja and Iina deepens, but at the same time the lies grow and make Senja's life almost impossible.
