there was this manga where the mc (girl) made videos on yt of her with a wig (pretending to be a boy) dancing. In the videos she said her name was Ai. And there was an idol who wanted to dance together with Ai, but in the end his company made them a duo, so they ended up living together in a dorm, because they thought that Ai was a boy. It's an old manga, it's shoujo and romance. If somebody knows this manga's title pleaasssseee help.
