The same Male lead in both dramas. Film gives a great performance. Both dramas have family conflict and an evil stepmother. Inheritance disputes, and attempted murder. A good mix of drama, romance and action.
If you want a lakorn with a ton of kissing, real kisses, and the couples mostly fail at hiding their feelings, both of these are a good fit. Both also have a distrusting ML who doubts the FL's character, but still can't stay away.
Very similar story, in that FL is asked to stay on as a manager for a resort when her boss goes missing presumed dead. Payu sai is much better, with a strong ML. Some of the cast is the same.
