Aya, what a tough child. I feel like this will really be the start when Sei finally sees Aya, but to free her from chain you have to shackle her with you. Basically, you can't just free Sei with that state of mind, you still have to hold her down. What I want the most is to protect Aya's love for Sei, it seems so solid and strong but it can also be shaken. If her feelings for her gets affected again, it may lead to something else, first, finally not caring about Sei, second, going insane and chain her down for real
