Was this licensed?

I don't think it was licensed, it's still ongoing in Japan (though it is complete upto volume 5, it is the 6th volume that's ongoing).
Searched on MangaUpdates, the group scanlating this was last active in 2017, it is an inactive group now, so this manga is most probably open to any scanlation group as long as they have access to the raws.

I hope it gets picked up soon, it is such a good story!
