5/6 of Saint Series. Maria Margarita is just a typical and normal intelligent kid in their class. She's friends with some but closer to her cousins, brothers, and sisters. She's a bit of antisocial and afraid of the world but a pageant monster at the same time. She'll meet River Lacoste, the guy who is known for his good skills. The guy who would bring joy and thrill to her teenage life, the guy who would break her young and fragile heart, the guy who she thought mastered the subtle art of not falling apart. In line between the two, there's always been a subtle action without knowing that they are already falling and both crashing.
