[Genshin Impact] I Went to Such Great Lengths to Give Away Primogems

A System came looking for me. It said its name was Savior System. [Everyone knows that whenever someone has an exclamation mark over their head, some goofy blond idiot will come running at full speed...] I get it. I'm supposed to be that goofy blond idiot? System: ...No, you're supposed to have the exclamation mark over your head. Me: ??? Little question mark, do you have lots of friends? In short, I have to give the Traveler Primogems so he can pull for characters and save the world. Me: So I give out the Primogems, the Traveler saves the world. What exactly do you do, System? System: Heh. I'm the one who made the Primogems. System: Hurry up and post a series of quests so the Traveler can get the Primogems naturally! Me: ...Here's the problem: how am I supposed to make a Mori Ougai-style quest with my bare hands? I wiped my face and decided to become a hopeless romantic. [Book of Love, Chapter One: Please help a poor girl deliver a love letter.] I thought long and hard, then confidently declared, "All right, let's send it to the Conqueror of Demons!" The Yaksha of the Wind looks like he'd be really hard to pursue. This is definitely going to be a quest series! Traveler: ...Is that why you made me handwrite a love letter? Me: It's not like anyone checks for plagiarism. Certain Yaksha: ... And then I won him over. Me: ??? Content warnings: 1. My writing isn't great, so please bear with me. The main story is in third person. 2. OOC. 3. The Traveler is Aether. 4. Original heroine, with plenty of original settings. 5. The heroine is a huge Liyue fan and sometimes goes a little crazy (?). 6. After ten chapters, the heroine's hair color changes and her appearance is slightly adjusted (?). Theme: Love cannot be measured in money.
