So lemme clear somethin up-
The relationships,
THEY'RE NOT ROMANTIC RELATIONSHIPSSS
Razor and Bennett, maybe yes since they're literally the same age as y/n
The relationships represent people y/n trusts and considers friends. The people she will literally call "friend" and be vulnerable around.
Y/n isn't really looking for a relationship. Heck, she's still learning how to communicate with other humans beings without immediately resorting to violence.
She's just trying to decide on what she wants to do in life. Her current goals are to help Aether find his sister and of course, bring down the Fatui.
As for her relationships with Childe, Diluc and whoever else is older than her, they're just friends in her eyes.
If they want something more, sure, but they'll have to wait.
Childe is simply her first crush.
She's learned to be protective of her family due to her time with Hilichurls, hence why she dislikes Donna and tends to be clingy around Diluc.
If y'all want her to have love interests, I'll either have to change her age or just settle with the endings set in timeskips.
Or I could just age down some of the characters that are older than y/n, that works too
You tell me. Personally, I'd prefer the endings since I'd already planned them out but I'll let this be your decision.
Baby Ushijima hopes you have a wonderful day/afternoon/night!
