I love exploring potential friendships between Shen Yuan and Shen Jiu in SVSSS fanfiction. I even think they're a fun slash ship! But I gotta be real: without extenuating circumstances forcing them to get along and work together in some way, I think they would hate each other.
This is part of the appeal for me! They can both be so prickly and mean (verbally, in Shen Yuan's case) that you have to forcibly smush them together to make a real connection, to summon any kind of kindness or compassionate understanding, and seeing that kind of dynamic character and relationship development is fun. It's important to characterization, in my opinion, if Shen Yuan in most situations starts out (rightfully, honestly) wanting to break Shen Jiu's kneecaps.
yknow the entire reason i decided to build virtual world was because of Virtual World Lulu. I mean she has my name (some friends call me lulu) and look at her
