There's no need to talk about what happened before the reincarnation. Back then, he was just an ordinary human, poor and aimless, struggling to make a living. Life was harsh, even the food tasted lousy. Even when his boss demanded mandatory overtime, he had to grin and bear it, desperate to keep his job and stay in the big city. Not a single complaint escaped his lips.
After being reincarnated into this world as a mighty Red Dragon, Leon's temper grew significantly worse, and he became increasingly intolerant of being wronged. Mainly because he started figuring things out—he worked himself to death in his last life, ending up with a tragic death. He refused to live that way again in this life. One should seek peace of mind while alive, after all.
Thinking back, from hatching to becoming a teenage dragon, spanning decades, he hadn't suffered losses often. But the few times he did were burned deeply into his memory.
