Honkai: Star Rail: The Aeon of Hope Is Perfect for Nihility

[Honkai: Star Rail / all characters × protagonist / romantic pairings / friendship / a little Sea of Quanta / updates are not guaranteed]

(The official love interests for now are Qiong (on the Imaginary Tree) and Xi (in the Sea of Quanta, an original character, though there isn't much Sea of Quanta content). The protagonist is blindly treated as the bottom, because I can't think of how to make someone who's sexually indifferent (yes, indifferent) take the top.)

Light and bland... probably?
