It’s a very easygoing drama with no second lead trying all sort of evil to exaggerated plans to separate the couple.
One thing that I really like about it is how everyone behave like adults!!! Adults actually acting like adults and not being overly childish or trying hard to be cute.

I feel like this is a story fangirls of KPop would really enjoy. The way the male lead supports the female lead will certainly make fangirls dream of getting such a supportive life partner!!
It was very relaxing and dreamy for me.
No big catastrophic twist, if that’s what you are looking for.

Though of course, as so many Kdramas, we have the not so shocking news that they grow up together or met in childhood.
