You and Nezuko were hanging out together, suddenly Nezuko pointed to Tanjiro, Zenitsu and Inosuke and said "they're really handsome, I wonder if they have a boyfriend yet?" You turned to Nezuko, "Let me ask you for their phone number." Nezuko happily nodded. You ran out and asked for the three people's phone numbers Tanjiro: "What are you asking for?" Zenitsu:"why did you ask for my phone number?"
Inosuke:"do you like us?" you:"no, my friend wanted to ask...." when you turned to Nezuko, she was gone (actually the three of them like you but are too shy to get to know each other so they make a plan with their sister Nezuko so they can get to know you :))) )
