It's my first time writing a review, but I felt like it was the right moment with this serie.
I wanted to depict what I felt while watching each episode, because I loved how each scenarios was a psychological travel that call out deep reflections.

Each episode has a different esthetic and scenery but It feels like a decortication process of this tricky human feeling of "Love and its variation" This special feeling that summons many different emotions such as : loneliness, jealousy, boredom, and tiredness.
Love in all its different aspects.
You can contemplate the personification of all these emotions through different storylines.

First episode, Love Set : A trouble tennis game between two girls who seems to be in a jealousy battle. They bet their own feeling to an intense game, full of violence and some points of erotism. It's really intimate, because the scenes contain many close-up shots, and it seems that the storyline was quite out.
But personally, I think everything is happening in gestures, faces expression and gazes. It's a battle of acceptance to each other emotions.

Second episode, Collector : A strange girl who seems to be emotionless, is collecting hearts, literally, in a surnatural quest of passion. She seems to be bored really fast, and seek the sparkles that ignite from new loves, new places. It is what I felt through this episode, her way to talk about her trip, the peacefulness she felt with the yoga and the fact that she seems bored by the limits of human body. It feels like she wants to test the extremes.
And naturally, what is more extreme than someone giving its beating heart to you...
The little box is significant, it seems to keep locked all the emotions of the male character. He keeps to restrain himself from blowing out until he gives his heart to the woman and finally lost his mind.

Third episode, Kiss Burn : I think there were many symbols inside this one. Passion through fire, anger, and getting rid of stress. These are the feelings I felt through the various plans.
"The adventure of the beach" and the kiss marks in the neck which relieved the stress of Hye Bok, a girl who was abused by his own father. This same father who seems to be abused by injustice. The passion of revenge which turns to be a fire that they had to put out and that ignites again. It's like an endless circle of situations who lead to an inevitable conclusion.

Fourth episode, Walking at Night : This one touched me the most. It's a simple discussion about memories and death with two lovers and how everything will eventually disappear in a blink of an eye. This makes us think deeper about the meaning of death, loneliness and love and how being surrounded by people won't prevent us to be alone.
I can quote this dialogue "Dreams & death lead to nowhere. They will end up nowhere and eventually be forgotten."
