Remember y'all, respecting the boundaries and giving proper after-care for your Sub is beyond important and the responsibility of a Dom in a healthy relationship!
I'm leaning towards low self-esteem Hinata rather than yandere Hinata. Wonder if we'll get a backstory of something like her having a male family member that abused and/or neglected her. Causing her to be this way. (God I hope that's not the case)
This is your reminder to drink water and remind your family members, especially your S-Rank Adventurer daughters, that you love them.
Happy New Year everyone!
