Childe's story quest but with a different ending.
Lumine teaches Teucer how to fight since his brother is busy selling toys in Liyue (at least, that's what he thought) Is there something similar to the both of them?
Lumine: Very nice, Teucer! You're easy to catch up!
Teucer: Hehe *scratches his head*
Teucer: Big brother told me that fighting isn't about looking cool, it's about knowing the reason why I'm fighting. And I want to protect sister Tonia!
Lumine smiles at Teucer. That's very sweet of him, she thought.
Paimon: Your brother told you that he would teach you how to fight when you get home to Snezhnaya, didn't he? So why would you want the traveler to teach you?
Teucer: I really miss my big brother a lot! But so is brother Anthon and sister Tonia! I don't want to take away all of his time just playing with me. Besides, big brother will be surprised because I've learnt some skills through you, miss nice lady!
Lumine: Well, let's take a break, shall we? Teucer, what do you want to eat?
Paimon: Yay! Finally! I am really starving for so long!
Lumine: I asked Teucer, not you, Paimon haha
Paimon: Hey! Paimon's been a great guide to Teucer too!
Paimon: What do you me- Hey! Where's Teucer?
The two made their way and found Teucer trying to catch a pigeon. He almost cried when he didn't caught a single one. The traveler decided to cook Sweet Madame since it's easy and Teucer loves sweet dishes.
Perhaps they shall tour to Mondsdadt someday?
Teucer: This is do delicious and so sweet! So this is called Sweet Madame?
Paimon: Yep! That delicacy is from Mondsdadt, a neighbouring city from Liyue. You gotta try the Sticky Honey Roast too!
Paimon: What's wrong, Teucer?
Teucer: I miss my brother...
Paimon: But we were just with him!
Teucer: Yeah, so short that it doesn't count! Let's go find my brother.
Lumine: That's children for you...
The three went to Qingxu Pool just to find Childe busy with the new recruits. It was getting dark but Teucer wanted to stay and waited for his brother even if he was sleepy. Lumine decided to take Teucer at the Wangshu Inn with Paimon. After that, she went back to where Childe was and wasn't even surprised that he wasn't even finished.
It didn't have to end like this. The only way to assure Teucer was to make a pinkie promise that she would await for his brother. Later, Lumine sat on the grass under the tree and eventually fell asleep.
Childe caught a glimpse of her...
The next one is gonna be written on Childe's POV
