The story is good except for the 2females' illogical behaviour. Especially the FL , her existence and thinking is beyond logic. They chose the wrong actress, she's too old to "act cute". Her illogical loyalty to her master is stupid and far better to be replaced by young sub-inteligent boy that the ML has a bond with,only a young sub-inteligent person can behave this way
This drama is watchable only if you can edit out the romance and the FL. The writer has made the two female characters to be unreasonably stupid, their behaviour defies logic
Without those two female characters then the story would have been perfect
Its a complete waste of a good plot but episodes 27 and 28 is really the peak of idiocy --no logical human beings behave this way
