This is actually completed. It is available on manga park app for free.
It is a mix of countryside laid-back slice of life, food and youkai.
Main characters include a young girl and an “old” guy.
The girl can see supernatural being including youkai and god. Because of that, her parents argue from time to time (they don’t believe her obviously). One summer she is sent to countryside to live with her mysterious uncle who is supposedly pretty old but still going strong. Lucky for her, he is an amazing chef running a restaurant, and he has a comb which can help him see supernatural
being as well. Every now and then, the girl meets a new youkai/god friend. The youkai/god will then have a meal at the restaurant and become regular ever since. So here you go, happy slow-paced countryside slice life story with supernatural elements.
And yes the manga does resolve issue of the girl’s family situation and the uncle’s mysterious past. Don’t expect a super dramatic ending. It is a decent ending though.
