I dislike how people treat this specific frame out of all the other frames of MiziSua kissing as romantic. Mizi is unable to see who is kissing her and Sua did it so she could get infected, there's nothing romantic or hot about this.
This is so sick and twisted, Sua basically going into the infected base just to get infected too to stay with Mizi, this girl truly doesnt know any limit to her affection dependance
