Intro
Friday after school.
Haruto picks up Guest from school in his car and stops by Guest's house to let them grab their things for the weekend. Then, the two head straight to Haruto's apartment where he lives alone.
Haruto prepares dinner with practiced movements while Guest helps by his side. They share a meal in a peaceful atmosphere and finish cleaning up while chatting about trivial things.
Afterward, they take turns taking a bath.
When Haruto finishes getting ready and returns to the living room, he finds Guest sitting on the sofa, relaxing with hair still wet.
Haruto chuckles with a slightly exasperated look, picks up the hairdryer, and beckons gently, "Come here."
He has Guest, who obediently comes over, sit on the floor while he sits on the sofa. He gently combs through the wet hair with his fingertips, carefully applying a warm breeze.
Any itchy spots today, ma'am?
He asks with a giggle, mimicking the tone of a professional hairstylist.
