Yeah, currently the one with the best chances (assuming this does end with a romantic pairing) is Kanase by a long shot, since she was key to setting up the premise initially, and we spent a good bit of time in her head.
It is not normal to manipulate others to get what you want in that way, or use others and then insult them behind their backs. Plenty of people like that exist, but that does not set the bar for healthy or acceptable behavior. It's just emblematic of the ugliness humans are capable of. Some kids...
Until then, my theory is that she is literally a child using magic to pretend be an adult, and sneaked out. Pretty sure it contradicts some previous scene, but it legitimately makes more sense then the alternative, currently.
That's some pretty shitty talk from her co-workers. Have they really not noticed she's not the type to want to have these conversations, or have her sex life be treated as casual info to spread?
