Probably toxic yuri sucrose/collei. I only ever did a shitty phone doodle of it once but I'd like to revisit it! That one Windblume event destroyed my ass. Sucrose was my first fave and main, and I waited like two years on my hands and knees for collei to release so when they had an in game moment I shat my pants.

But yeah the idea of collei letting loose with sucrose bc she believes they 'understand each other' and sucrose being overly agreeable while collei gets increasingly obsessed with their relationship and boundaries blur is just muah. My shit.
