Miira no Kaikata, Jingai-san no Yome Recommendations
Similar moods and situations, though one is about absurd marriages and one is about pets. There's not much to think about in either, but can be enjoyable if you are in the mood for very simple and lighthearted monster stories.
Both series have a similar art style and involve protagonists interacting with monsters. Jingai-san no Yome takes a more romantic approach while Miira no Kaikata is platonic. They're both strange, sweet shows with a similar feel.
Despite the fact it just came out, I get serious Miira no Kaikata vibes from this, the art, and the premise of a boy coming into contact with a creature along with friends also with creatures. So if you wanted a light hearted anime with a school setting that isn't a slice of life romance this would be it. Also with the added twist of a random cute squishy thing.
They have the same vibe, really relaxing and full of cute weird creatures attached to humans
Teens still in school having platonic relationships with creatures.
Cute and funny.
