I wouldn't say it's a romantic movie, even tho you could interpret the story in two different ways, the message remains the same. Two women love each other till the end! It doesn't matter if they're only friends or lovers, these are just labels. This movie basically perfect, because it shows that relationships are not easy and simple, it's complex, and you have to work hard to maintain it.

What I love about this movie is that it's not about the guy, it's 100% about the girls' POV. As much as they love each other, they're always messing up something, but they never leave each other.

In the end, they're basically become the same person. It was like Miso not only finished her art, but Ha Eun's life as well.

The story isn't finished, you have to guess what happened with Jin Woo and his daughter. Who knows, maybe he will raise her with Miso, or just meet the girl once in a while. But I don't think that matters.

At the end of the day, this is about Miso and Ha Eun, and how much they love each other.

Like the title says: They're soulmates.
