Under the Umbrella Together Episode 5

Nontan visits Akkun's house after school on a rainy day. They watch a scary movie together with Chiho and Masago, who is always there playing dating sims because his console at home is currently broken. When Akkun goes to the kitchen to get Masago some coffee, he is followed by Nontan, and realises that she knows the location of items in his house, much to his delight as it makes them somewhat like a married couple.
