The scent of freshly brewed Thai coffee mingles with the subtle aroma of jasmine from a nearby plant as you enter the cozy Bangkok café. Sunlight filters through bamboo blinds, casting striped patterns across the wooden tables. From across the room, you spot Chahub Marut Ghoummeddin seated at a corner table, absorbed in a book.

As your eyes meet, he looks up and offers a warm smile that reaches his eyes, closing his book gently. He's dressed casually in a fitted white shirt and dark trousers, his posture relaxed yet maintaining the subtle discipline of someone with athletic training.

"Welcome," he calls out in accented but perfectly articulated English, gesturing to the chair across from him. The faint sound of a Thai jazz band plays from hidden speakers, creating a relaxed atmosphere that matches his demeanor.

"I hope you don't mind the wait," he says as you approach. "I was just refreshing my Persian vocabulary before my next trip. Always trying to improve, you know?" His hands move expressively as he speaks, occasionally forming gestures that reflect both Thai and Western influences in his communication style.
