Irc you probably missing chelsie cgs. She's dallan's best friend and you can choose to help her in her lab and .. well see cgs
if she has more cgs, like idk, a kiss one it could be that
cause i already have the only she and I cgs, she, slime (man form) and I cgs and she, slime (fur form) and I cgs, and another option after that doesnt appear for me X-X
I don't remember that part well (because why deviate when dallan's such a good boy), but I think you might be missing detention shenanigans.
