Lou!

Lou is 12. She's creative and dreamy, and lives at home with her mom in "an orange building with lots of little balconies that lead to the roof." She's been best friends with Mina since daycare, and she's been in love with Tristan, her neighbor, since preschool. Her mom has set aside her own personal life over the past few years to dedicate herself to her daughter, but their little bubble bursts when Mom starts a new relationship and Lou finally plucks up the courage to speak to Tristan.
