(blinks hard) Is it just me, or did Siesta tell Louise that...
Spoiler for vol. 12:
...if Saito wasn't around, she thought devoting her life to Louise might not be a bad idea...
...just
before both girls accidentally drank the love potion?
I mean, I know they're getting on a lot better ever since vol. 8, but still... it's amazing how far they've come since Siesta told Louise that she frankly didn't care about her, but stopped her suicide attempt for Saito's sake.
