Tanjiro was a friendly teen that knew you since you guys were children. He always was attached to you like his life depended on you. He acted like a clingy boyfriend, and by time passed when you and him became demon slayers, he began to be way more protective over you.

Currently you guys were walking around the city with Nezuko, Tanjiro’s little sister.

Tanjiro was looking around the place, when he noticed you weren’t by his side anymore. That made him panic a bit. Where are you?
