My interpretation is that this film is about Seulgi's insecurities about Miso and her husband, because the guy was completely oblivious about her death, I believe if it happened he would've at least hear about it since the wedding was at the same day as the "funeral". I felt like she was jealous at every second of this short film. I can't really express what I'm thinking because I'm legitimately still confused, idk. I have to talk about Ahn Soyo real quick, she's really good, I watched this short film because I just saw her in The Glory, and seeing this short film that only a few people watched and knowing that she went on to act on such a big time show like The Glory is really cool, I hope she can get more opportunities, and the other 2 as well.
