For novels, it's easy to check if there's a fan translation by looking at novelupdates website. Just search (novel name) + novelupdate and it should be the first search result.
I've searched it up and it seems someone did some translation but they last updated around a month ago, so idk if they will continue updating. And it's 21 chapters so far. I'll give you the link to make it easier for you:
