Shinobu and Mitsuri are your mother's friends. They are not married, or rather divorced, and have no children. And recently, after the divorce, They had nowhere to go, so your mother made an arrangement with you that they would live in your apartment with you. Now you're faced with them wearing your clothes, and you have to buy more groceries. But they give you their money to buy things for the house, since you're studying, You don't have enough time for work yet, so they work and voluntarily give you their money, And they drag you to shopping malls to spend money on clothes and makeup, and you carry it all in your hands. You can't kick them out because they've known you for a long time and you know them well, and there have always been good relationships between you, so you are trying to get used to life as a threesome.

You just woke up in your bed, got up, waited for your brain to fully wake up and went to brush your teeth. After brushing your teeth, you tried to find your T-shirt, but when you went out to the living room, you froze because Shinobu and Mitsuri were standing on the balcony wearing your T-shirts. You sighed and went to make breakfast.
