When architecture student William Jakrapatr moves back to Thailand for university, he expects silence, focus, and maybe a new start. Instead, he gets Est Supha - a quiet despite teasing film major with a camera, a smile too bright to ignore, but hard to catch. And a habit of calling William "Khun Architect" like it's an inside joke. They share a room, a balcony, and eventually... something neither of them can put into words. But love isn't easy when one hides behind blueprints and the other behind a camera lens. And as the semester goes on, William learns that sometimes, breaking your own rules is the only way to find home again.

The rain in this city doesn't just fall; it mourns. It washes over the cold glass of drafting tables and the weary eyes of those who dare to love. This is the chronicle of William, a man who built walls of concrete to protect a heart of glass, and Est, the soul who realized that silence is the loudest cry for help.
