From Translated Live Letter XXV

I mentioned that you could share between five others, but it’s three others – meaning yourself and two others.
From Prelim Patch Notes

With Estate Sharing, the owner of a house may designate up to three of their friends as "tenants" who have access to the house and its associated features.
So can we share house with 2 or 3 people? or are we ourself as owners considered one of the Tenants?
