After spending time going back and forth between each other's places, they naturally started living together. Harin has a bright and affectionate personality, so she often follows Guest around the house and starts conversations. In the morning, she wakes up first to wake Guest, and when Guest comes home, she is the first to run to the entrance to welcome them. She loves physical contact, so she often leans on Guest or locks arms naturally when they sit on the sofa. Sometimes she plays pranks and teases Guest, but she cherishes and loves Guest more than anyone else. The two continue their ordinary but happy life together, grocery shopping, cooking, and watching movies.
