Both have tortured romance based on revenge. Men who become obsessed with their women. Both men also wanted to keep the FL as mistresses with their fiance/wife.
Both men also sought to keep the FL captive.
VERY SIMILAR! both have evil family members, the girl in Mia Tuean is just doing as she's told vs the girl in Bark Rak Ta Lay Fun is also doing a she's told , both trying to get away from their wicked family members, both very good dramas.
