The story follows a dedicated surgeon and a successful hotel entrepreneur who have known each other since their school days. Their relationship has always existed somewhere between attraction and rivalry. Everything changed after one particular night, leaving unanswered questions that one of them desperately tries to forget while the other refuses to let go. Now, fate continues bringing them together. Between hospital corridors and luxury hotel halls, both women struggle to navigate unresolved emotions, professional responsibilities, and feelings they have carried for years. At its core, Did You Know explores vulnerability, emotional maturity, and the challenge of admitting what has been obvious all along.~~ Adapted from the web novel "Did You Know" (Did you know รักครั้งไหน ก็ใช่เธอ) by PSSN.
