The story is really beautiful, it's dark but with a fine undertone of hope. The actors did really great and my heart ached for them. The way they interacted with each other was so careful, in a scared way, and the kiss showed their attraction to each other and their fears at the same time.
The colors were muted, it really felt gray, like a heavy blanket for your emotions. Beautiful!

The OST is perfect! I often skip the intro and outro, but not this time. It reminds me of my fav anime "NANA", it has the same underlying feeling of hurt and lonelyness, but with a powerful beat.

If you like more mature, dark and serious stories, you should watch it!

I read in the comments that a second part is possible, so maybe we get to learn more about their story. I would really like to see more of those two broken people, how they maybe get a "happily ever after" or even a "both starting to heal". That would be enough for me.
