I Was Reborn as His Highness the Prince's Little Evil Dragon

I, Bian Yurong, had lived 18 peaceful years with good grades as a college student and making good money as a game streamer, when I was randomly killed by some criminal. What's worse, I'm reincarnated into my favorite game as its endgame boss, the black dragon! I know how the game goes, so I'm going to take charge of my own fate! But wait, the crown prince who's been taking care of me, something's not right with him? (Source: Bilibili, translated)
