My Prince Is Truly Steadfast!

Li Huai catches the last train of transmigration and arrives in a world called the Yu Dynasty, where he becomes a dim-witted imperial grandson. He plans to rely on his adoptive Crown Prince father to live out a carefree life, but the Crown Prince suddenly dies a tragic death. Branded with the charge of patricide and driven out of the capital, he is so down on his luck even the dogs on the roadside shake their heads at him.

The officials: Please stop keeping your head down and start acting like a person.

Emperor Yu: My good grandson, what a fine grandson!
