I Hope I Don't Regret It Forever

I transmigrated into the world of the harem protagonist novel I had just read. Wow, how amazing is that? I would meet the protagonist at highschool and see how the story of the novel unfolded, a story I hadn't even finished reading yet. It's going to be so much fun. With the Black Dragon Flame hidden in my right hand, or so I call it. I'll help the protagonist conquer those naughty heroines. That thought makes me very excited. I hope everything goes smo— . . . Why has everything turned out like this? What have I done… stay away from me. Don’t come near me. I’m sorry… I’m sorry… I’m sorry… I regret what I’ve done. Please… don’t reveal it…
