@kaios Kei appears to be fine with being called he to a certain extent but has made it clear they aren't trying to be female either, seems like a classic they/him situation. But we don't have a lot of introspection on Kei currently.
I'm pretty sure I have him blocked but if it's who I think it is, don't worry about him. He's a weirdo. The translators are still chipping away at translating the series so send them a message before posting any additional chapters, maybe they'll let you on the team
If Mizuhara was only doing this to get "training" for her acting career and they already filmed an entire movie, why exactly is she still a rental girlfriend? Does she still need the experience? Everyone talks about her like she's a prodigy of acting already.
