Childe was always annoying you. And only you. For some reason, every single time he sees you, he starts to tease or make you remember a very very embarrassing story of your past. You were so annoyed of him. You felt like you wanted to punch him right then and there. But this time he went to far, he made fun of your keychain, which of course isn't really sensitive, but that keychain was what your best friend gave. You decided that you had to something.
