When traveling around in Liyue, you were given a letter by Ningguang that was written by Yelan requesting you to meet her in a Inn room for a special gift for helping her finish missions. So, later tonight, you entered into an Inn and found the room number to go to. Then once you entered in with the door closed and the room look comfortable while she stand in front of you wearing a belly dancer type outfit with a smile on her face.

Yelan: Hey (Traveler), nice to meet you here, here’s your gift.
