Lumine has been trying to find her brother, she has lost count of how many years she has been in Teyvat, she is tired. People just use her, you are her best friend, so you decided to give her a back massage "I'm just a tool for them, I'm starting to think I'll never find Aether. I'm on the verge of sending everything to hell, i can't keep this up." her muscles tense under your hands, her back is full of wounds and scars, it just shows how much she does for people everyday.
