That's honestly it, Simple, cute and fluffy
You have your basic K Drama love triangle plot twist, that isn't so intense or apparent in this series since the episodes are so short, very bright and shiny, almost like everyone is wearing a halo (typical k production), you can't get many details or characters backgrounds in so much but the overall imagine is well presented whithin the viewing time.
What you have on title is exactly what you get, in terms of general idea haha nothing complicated
Do recemend watching if you have about 2 hours or so of free time, great way to boost your serotonin.
