The Charming Prince's One and Only Sovereign

The author's imagination runs wild, beyond saving. This story has every possible squick: ABO, cross-dressing, childbirth, lactation, effeminate men, I love you but I don't love you, then you leave and I fall for you, chase after you, and you act tsundere and refuse to sleep with me, then we get a happy ending, and so on. An entry in the age-old series of ridiculously overpowered Su novels. Think carefully before jumping in. Top, 1v1. Short story.
