Yup this is the best Romance drama.
They are attracted to each other from the start and they started dating very early like in episode 9 they shared their 1st kiss and to the people who are commenting that FL is very amateur what do you expect from a 21 year old girl who was never in a relationship and just started a relationship in foreign land.
She feels shy while kissing him in public , that's why she avoid kissing in public and after some time she started taking initiative to kiss him,hug him.
One of the reason why I said this is the Best Romance drama was because there is no misunderstanding, a lot of kisses and a very happy ending.
There is only a little argument in episode 18 but that's it , It got resolved in episode 19.
There are a lot of sweet moments.Also The background songs are so good.
