Gap is the mother ship of Thai GL. The meteoric international success of Gap and the abiding popularity of the two main characters, Sam and Mon, and the actors who portray them, have established Thailand as the undisputed leader in the Girl Love genre and paved the way for what has become a steady stream of increasingly professional and well crafted GL dramas.

Even though many new series have followed Gap, this groundbreaking show still rates as the best loved and most watched, likely owing to the openly affectionate and trusting relationship between Freen Sarocha and Becky Armstrong. Their on-screen chemistry and the realism with which they portray a deeply loving relationship keeps them the preeminent GL couple in the industry.
