I absolutely love this show. I know some people don't like shows that have "sad ending" in my opinion, if this had a happy ending it would have been so forced and weird. Considering how their relationship started to fall apart by the end of the show.

The ML really was focusing on his career and in the beginning of the show he also had a clear goal in mind; was to help bring his family together. So the relationship, though was sweet, it was never gonna last
She didn't want to have someone who was rarely there and who couldn't be real with his feelings plus, considering she already went through the same thing with her mom, who was barely there for her.
Her mom always put work before anyone that includes her own daughter. I don't think the news channel ever even found that that one of the most famous fencer in Korea was the news caster's daughter. Pretty wild lol her mom was something else lol
The show is so well written though. All characters are amazing and super likeable. You get to know and love everyone

The FL here is super likeable, funny and caring and good ML as well.
He can actually act when the materials required him to.

The SFL is also good. Though, I didn't like her at first but as her story progressed , I learned more about her and her struggles and she ended becoming very likeable after she solved her issues with the FL and she got a happy ending. So, for people looking for a good or cliché relationship. There you go. I loved that she kept losing to the FL ??

I would definitely revisiting this show again in the future. I saw some people skipping last two episodes don't do that. You won't get the full story if you do.
It's not a sad ending, it is the perfect ending.
10/10
