This is definitely underrated
I don't know if people got filtered by the gacha game premise or the dull first couple chapters, but it has a lot of fluffy moments. The cuteness is definitely on par with other series that have more popularity and higher ratings. If you like casual fluff and have a basic understanding of gacha games, I would give this series a try. It's good, despite it's 7.90(as of this comment) rating.
