It starts as a very sweet romcom, with nice faces and funny encounters, mouth-watering recipes and everything... The mature ML has great chemistry with the FL, but the writers decided otherwise, and despite the reciprocal love and tenderness of this couple, they make some twists and pair the FL with the immature younger ML ! Honestly, i didnt like this, it's like saying that being hard-working, dedicated, sensible etc etc values nothing on a personal level! Also, it's nothing funny when you pull out the amnesia trick and make the ML forget the love of his life.
My guess is that the director was biased and wanted to give credit to the popular korean ML...
