Their story starts with jealousy from one person and ends up being cathartic for both of them. Cha siwon's struggle and his childhood being the trigger for the initial interactions between the leads.

The ost and cha siwon's bickering adds flavor to the slow burn emotional journey the characters go thru. The cinematography and shots are soo good . It's a kdrama so it's expected but some choices made for the visuals esp ep 9 and 10 reflect the characters emotions in the backdrop. (The shots feel like a jdrama and early k romcom movies)

It maybe confusing sometimes but it's the director's way of storytelling so I can't really put that as a negative remark.
