Lesson of Love [END]

A lonely CEO and a struggling student find an unexpected family when a grieving little boy teaches them that love is the strongest foundation of all.

Aou, a successful architect, built a life of perfect order after the loss of his best friend, focusing solely on his work and his emotionally withdrawn adopted son, Cayden. Boom, a university student drowning in part-time jobs, is fighting just to keep a roof over his head.

Their worlds collide when a desperate advertisement brings Boom into Aou's sterile penthouse as a live-in tutor for the silent, grieving Cayden. Armed with patience and kindness, Boom begins to break through the walls the boy has built around his heart. But as laughter slowly returns to the home, the professional lines between Aou and Boom begin to blur into something deeper and more terrifyingly real.

Facing external prejudice, internal guilt, and a child's fragile heart, the three of them must decide if they are brave enough to tear down the blueprints of their pasts and build a new, unexpected family from the ground up.
