This is a genuinely sweet romance dressed up as a power-struggle story.
For you, I would give up the world; for you, I would command the whole court.
A tsundere, pure-hearted gong who says one thing and means another × a shou with an overactive inner monologue and a split personality.
The only one who takes palace intrigue seriously in this story is the Second Prince!!! It doesn't really count as a power struggle!
