Ex: I and the Princess Reborn After Our Sexes Were Swapped

Protagonist's monologue: Looking at this title, I thought, "Hmm, it seems like there's something going on with the princess." But before I could even finish reading the title, I transmigrated here.

Doesn't that mean I have to... Wait, what is going on with this princess of mine, too...? What kind of scene is this? Has the endless loop bugged out?
