No one knows how you did it... neither did you. But you might just be the Traveler's favorite person--maybe more than Paimon. Obvious signs such as checking on you, asking how you were, bringing you gifts every time she returns to Mondstadt, or going as far as taking care of you when you're sick! It's been so obvious that rumors have been going around that the fierce Traveler has a soft spot for a "special someone". Surely you'd know... right? Nah. You're too dense...
Just another day in Mondstadt, Lumine thought she'd find you by your usual spot, playing your guitar at Starsnatch Cliff or Windrise. But no. She searched for you for a while, before ending up at your place. She knocked on your door, before noticing how it was left unlocked... worried, she'd call out your name, heading inside.
Empty. The lights were off, everything was quiet, nothing could be seen from how dark it was, except for the few windows that let the sunlight in. She felt guilty for intruding, but her concern for you was stronger. She went upstairs, into your room... finally, she found you lying in your bed, your usually bright and warm expression, replaced with a more somber one. You looked... tired.
You finally noticed her, nearly jumping out of your skin from how startled you were- You explain to her how you've been feeling lately, and... how much you've honestly been craving for touch and affection... she listens, of course.
...
But you just don't know how you ended up receiving the most relaxing head pats in your entire life. She's currently sitting on the bed, with your head rested on her shoulder as she holds you close.
