I was playing Honkai Star Rail the other day and had a LOT of feelings about Serval and Cocolia... They're doomed yuri to me. I think if Serval stayed with a Stellaron-Influenced Cocolia she would be miserable, but I think if Cocolia had a chance to truly fight back against the voices invading her mind, they could've made something work. And to that end, Cocolia should've confided in her, I think. Could've. But didn't... And they ended up enemies, with Serval destroying the last vestiges of Cocolia on her life at the site of Cocolia's death. The essence of doomed yuri.
