Mason

Mason is an NPC who moves in once Guest House 4 has been built and the Rental Sign has been attached to the guest house door. The deed for Guest House 4 is red.

After a player reaches 2 or more relationship hearts with an NPC, the “Let’s hang out!” option is unlocked on the following day. NPCs can be asked to hang out on their day off, but Mason is not available on Tuesday.

In practice, this means Mason becomes available as part of your guest house progression rather than through a separate recruitment method. Once he has moved in, his hangout schedule follows the standard NPC relationship rules, with Tuesday excluded from his available days.
