My Boyfriend Is the Regent

[Morbid, calculating, white-cut-black, laid-back emperor top x Rebellious, arrogant, ambitious traitor bottom]

When I was eleven, I was an unfavored prince, and Wen Tinglin was my study companion.

When I was sixteen, I was in Yecheng, while Wen Tinglin was in the northern desert.

Later, when I was twenty-one, Wen Tinglin marched south with his army and breached the imperial city. He walked toward me, the tips of his twin crescent halberds scraping along the ground, leaving a trail of bright red blood blossoms.

He had always been beautiful, with a bewitching, exquisite face. Even with frost in his expression and blood on his skin, nothing could diminish his stunning appearance.

With scarcely any of the imperial family left, I didn't dare think of striking up a friendship with him. I closed my eyes and waited for a quick death. With a sharp clang, his twin crescent halberds struck the ground. Wen Tinglin bowed before me, his voice just as it had been in the past: "Your servant greets the new emperor."

I froze and opened my eyes. Behind him, I saw the ministers who had hurried over at the news, and the hatred in Crown Prince Brother's gaze.

Amid the shouts of "Long live the emperor" and the sound of people kneeling, all I heard Wen Tinglin say was, "Don't be afraid. Your big brother is here."

[First, may our land be safe and our world at peace. Second, may A-Sheng live a safe, smooth, and long life.]

Reader's guide: 1. The main story is in third person, from the top's perspective.

2. Three-year age gap. The top calls the bottom "big brother."

3. The bottom is extremely career-minded. He chooses the top as emperor because he thinks the top is easy to control (or so he thinks). The top is a college student who transmigrated and only wants romance (or so it seems; when his love-struck side goes off the rails, it's terrifying).

4. To be added when I start writing...
