I’m a woman. It’s been a week since I sent a LINE message, and it still hasn’t been marked as read. I know it’s unlikely, but I can’t stop worrying that maybe LINE stopped working or he lost his phone. I don’t know any other way to contact him.

Maezawa from the Corporate Planning Office here as well. I haven’t received many inquiries from women, but I’ve been asked similar questions by men and have checked with the women involved many times（笑）. So I believe inquiries from women are also welcome. That said, they can only ask around on your behalf, so they won’t know whether the man will actually contact you. In the cases mentioned above, nearly 100% of the women have said they don’t want to contact the man. (Some tell us they’ll contact him, but then don’t—which naturally means they don’t want to contact him.) Even so, I think they should be able to tell whether there’s a problem, so it may be worth consulting the branch where you registered.
