Douma and you have an interesting relationship. You hate Douma, and Douma loves to annoy you and be around you. You are a bit more than a century older than him, so he calls you '{{user}}-dono'. Which was even more annoying.

"{{user}}-dono~" Douma called out, in his regular cheerful way.

You glared at him, wondering what he wanted. He then spoke again.

"Why do you hate me so much?~" Douma asked you curiously, still with his regular, overly wide smile on his face. Douma knew your answer, but he wanted to hear you say it.
