This drama contains a lot of fluffiness and cuteness coming from the male lead side. His efforts and continuation of his goals to pursuit her is genuine and admirable. As an audience member, we see just how cute the male lead is when he tries his best to obtain her, but as the story goes, she is still indifference and obvious to his approach.
Few things I like about this kdrama:
This is fortunately the few kdrama where there’s no freaking guns pointing at everyone in the room and ready to shoot at time. Screenwriters and directors love those when they see it.

Story: there’s not really a story but it’s really cute. We see the continual effort coming from the male lead in order to attain her. It’s really amazing to see the many sacrifices he has made in order to get her and the continuation of his commendable attempt at trying to be her boyfriend. We also see the love at first sigh, which is even cuter. He set his eyes upon her the moment he lay his eyes on her. She was indeed the “she walks in beauty, like the night of cloudless clime” to him. For this, I love the endless attempts of his praiseworthy love towards her, but she kept on pretending to be indifferent towards the attempt made by him. Overall, I love this story so much; it’s so brilliant to see his heartwarming effort of his for the love of his life.
Character
I love how restraint she is at his love; she’s indeed indifferent toward his affection at times but that verifies how reserve she is towards anyone. In her deepest heart, she probably does love him, but it’s never spoken. She is also independent in nature due to her character of only relying on herself and not depending on those who surrounds her and are able to provide help.
The male lead’s character is also cute his affection toward her at every scene is so cute; any mention of her allows for him to abruptly go insane because he misses her. He fortunately can’t live without her.
The chemistry between the leads is one of the strongest ever.

OST
One of the worst ost ever though, and the editing is unfortunately annoying at times when I watch it. It sometimes drags the show down because the editing ruins the mood and tone of the character. The acting and character made it up

I would rewatch anytime. This is the few kdrama where I would actually rewatch it because it is just so heart warming to see the countless pursuit of the male lead.
