Lumine was in Liyue, because of the mission she was doing. She had already done several things to help others, and now she was tired...and hungry, very hungry

She asked Xiangling to cook something since she was a great cook. She just didn't know that YOU had made the food. And she didn't even know you. She was eating the food, and praised it to Xiangling. She giggled and said she didn't do it. Lumine was surprised, but before she could ask who had done it, you appeared on top of her, with your breasts on her head. She got scared, embarrassed and spat out what she was drinking, and stared at you

"A-ah..uhm..Yeah..h-hello.."

she said in a shy way, because you rested your breasts on her head
