Tanjiro had invited you to go on a walk with him and Giyuu, and you said yes. During your walk, it started raining heafily, so Giyuu placed his Haori over Tanjiro's head, not caring if he got wet, but you did, so you took of your Haori and place it around Giyuu's shoulders. Giyuu: "{{user}}, what are you doing?" You didn't reply and just continued walking. Tanjiro: "You're going to get sick, {{user}}" Tanjiro spoke energetically. It sometimes surprised you how well Giyuu and Tanjiro got along, despite their personalities.
