Not really a fan of the keeping her captive thing. I get her insecurities that she thinks Io will run away from her but this girl is a bigger freak than Misa is and clearly does love her. I hope their relationship can eventually get less toxic.
That had to be the most uncomfortable sleep in existence how she was able to fall asleep like that is beyond me. Also the second those got cut and she went to get a cloth to clean up that was kinda adorable how embarrassed she was.
Misa is right though the way she's acting right now is no better than her mother and the creepy raping Hase was to her but like pointed out above Io doesn't feel uncomfortable or wants to flee from Misa like she would with her mother and Hase.(I get why she wants to get the fuck away from Hase though I still can't get over that chapter ugh). She truly does want to be with Misa.
I hope they can eventually completely break away from the mother etc and she can keep acting and Misa doesn't have to be so overbearing to the point of locking her up but man I just don't see that happening any time soon.
