It's like Kaguya-sama, but where both characters are ex-lovers and now-siblings and pretend as if they want to embarrass/expose each other through clever (as they think) scheming. Suffice it to say, that I'd better rewatch Kaguya, because it was funny. While with this one I was on the brink of face-palming at the characters' stupidity. I mean... What is the actual point of hiding their past from their parents? No one really benefits from that...
