The male leads (both the teen and the adult) were just absolutely phenomenal in this show. The teenage girl and the adult woman FL didn't look much alike and that was honestly distracting.
Some of the camera shots looked like paintings, especially at the beginning of each episode where they'd show the title. The still shot with the title was always absolutely beautiful.
It's not comedy, but-- like life-- there were some funny parts.
It's mostly sad, with a bit of hopeful and happy. I do have to say, I didn't understand the hero's reasoning in episode 8, it make no sense to me. Nor did the heroine's choices right after. It would've been good if they'd talked to someone to spell it out for the audience.
