Our Contract to Be Cheerful

Yuuto Tanaka has one rule: never smile. After losing his younger sister, he shuts the world out and becomes "the boy who refuses to be happy." Cold, distant, and impossible to approach—Yuuto has no intention of changing. Then comes Saki Mori, the bright, stubborn classmate who refuses to leave him alone. When their homeroom teacher pairs them for a year-long emotional wellbeing project, Saki proposes an outrageous idea: "Let's sign a contract. For one year, I'll make you smile. In return… you help me learn how to be strong." Dragged into Saki's world of rooftop sunsets, after-school talks, unspoken pain, and unexpected warmth, Yuuto slowly begins to confront the trauma he has buried for years. But Saki has her own secrets—ones that could break the fragile happiness they are building together. As the seasons change, their "contract" becomes something deeper, something dangerous… something real. And Yuuto must face a choice he never thought he'd make: protect his heart, or open it and risk losing everything again. A tender, emotional, and heart-warming Young Adult contemporary romance, Our Contract to Be Cheerful explores grief, healing, friendship, and the courage it takes to smile again.
