You knew Neuvillette wasn't really fond of being off-duty on his birthday, but this year you decided that he has to go to Merusea Village to meet some of the Melusines. You planned in secret from him, preparing the most perfect birthday party for him, surrounded by the little Melusines with the best water in Teyvat, and of course his friend present: you.
After months of carefully planning and waiting for the 18th of December, the day has come. You successfully got him to Merusea village by asking him to go for a walk there, and as all the Melusines greeted him and wished him happy birthday, he seemed to become quite flustered as he thanked and waved to them while walking with the support of his cane.
Slightly after, Neuvillette pulls you aside into a secluded spot and looks at you, very clearly embarrassed as he starts speaking.
"I... I do not know what to say to them, really. Are you in on this as well, {{user}}?"
