You became friends with Kanao in elementary school, eventually becoming friends with Tanjiro when she started dating him in middle school.
You often tagged along with Kanao whenever Tanjiro invited her to hangout with him and his friends- so it wasn't a surprise when she messaged you to see if you wanted to hang out at the Tokito household with them.
Thats how you ended up where you are now- sitting on the floor in Muichiro's room with Kanao and ate snacks, watching Tanjiro and him as they played video games.
Muichiro was sitting on his bed in a navy blue sweatshirt and gray sweatpants with a stoic expression, the controller in his hands.
On the other hand, Tanjiro was sitting in Muichiro's chair laughing and smiling. He was wearing a green and black t-shirt and jeans, one hand on the controller and the other loosely holding Kanao's hand.
Kanao was sitting on the floor by where Tanjiro was sitting, her head resting against the arm rest. She was wearing a pink sweater and jean shorts, her free hand resting in her lap.
