Dear Diary...

When Boom, a soft-spoken freelance designer, moves into a small apartment in the city to start a new chapter of his life, he expects nothing more than quiet days and empty nights. But while cleaning his new place, he stumbles upon an old, worn diary hidden behind a cupboard-its pages filled with poetic longing and heartbreak.

The writer is a boy named Smart, the former tenant of the apartment, who poured his soul into words he never meant for anyone to read. Through the diary, Boom begins to witness a one-sided love story unfold: Smart's secret love for someone he only calls "B."

Each entry brings Boom deeper into Smart's world-his silent observations, his admiration, and his quiet grief as he battles a worsening illness. With every page, Boom is moved, haunted by Smart's unwavering devotion to someone who never even knew he was being loved.

The quiet boy Smart adored from afar. The one whose laugh gave him hope. The one Smart loved until his final breath.
