Demon hunter's Cooking Manual - Chapter 890 - 64 A Meal Causes a Sudden Increase

I possessed a minor character who marries the prince. I’m not thrilled about it. The prince is a scumbag who flirts with the heroine despite being engaged and eventually gets defeated by the original male lead. In the epilogue, all he does is apologize to his fiancée and marry her, with barely a line to his name. Well, his personality is twisted, but at least he’s handsome. And since he’s the third prince, he doesn’t have to shoulder the burden of ruling the kingdom. That’s decent husband material, I suppose. Go ahead, make a fool of yourself. You’re going to marry me anyway. I’ll just sit back and enjoy watching your embarrassing history unfold. “Doris Redfield. Don’t expect me to ask you to dance at this ball. Maybe not at the next one either. Or the one after that.” “Yes, Your Highness. As you wish.” “Even though we’re engaged… wait, what?” “It’s just a joke proposal our parents once tossed around, isn’t it? You don’t need to take it seriously, Your Highness. I’m really fine with it.” “…Is that so? Yes, that’s… fine, right?” Why are you panicking, prince? You started spouting nonsense first. Where’s your conscience? But then, this guy really has the audacity to ask something outrageous. “…Do you, perhaps, have another man?” The guy who flirted with the original heroine is saying this now? Calm down. He’ll regret this later. All I need to do is remain a devoted fiancée until then. “What are you talking about? A woman like me… plain, not beautiful, with a gloomy personality, what man would even—” “What? Who dared to say that about you?” …You did, in the original story. This guy is acting weird. But he’s not the only problem. “My dear little sister Doris, that dress you’re wearing today is dreadful. No wonder there are rumors His Highness has abandoned you.” “Well, it can’t be helped. His Highness is too good for me anyway.” “…Hold on. Too good? Who said that? Wait, were you really dumped?” The original villainess, who also happens to be my older sister, Natalie, is suddenly interested in my love life. Why are all the original tr*shy characters growling at each other over me now?!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

“Where did he go?” I murmured, realizing I was alone.My heart sank as I scanned the room for any sign of him. But It was just me, an empty wine bottle on the floor, and memories of the night before.I pushed myself up, feeling the dull ache in my body.The alcohol still lingered in my system, and I had no idea how many times we had... well, how many times we had done it. But despite everything, I couldn't deny I had enjoyed it.“You're such an idiot Kim!” I scolded myself, running a hand through my messy hair. “You didn't even ask for his name.” I sighed, embarrassed at my recklessness.How could I let myself go low with a stranger like that?I glanced down, realizing I was completely naked. “Oh my gosh!” I yelped, grabbing my dress off the floor and quickly slipping it on...★★Humiliated and betrayed, Kimberly Fray's life as a powerful Alpha's daughter of the Moon Stone Pack crumbles when Alpha Derrick of the Night Walkers Pack rejects her.But as she uncovers her true identity, Kimberly finds herself caught between two ruthless Alphas who desire her.Torn between Alpha Derrick, who begins to see her worth too late, and the Alpha King, Kimberly's strength and courage are tested like never before.In a world where love, revenge, and power collide, Kimberly must decide who she truly is, and who she's meant to be with between the two Alphas chosen by the Moon Goddess!

“For a long time, we humans have been like the chosen race, without any natural enemies, and have long been at the top of the food chain. Unfortunately, I have to tell you...” “When there is only one bird in a forest, then the forest is basically fake, and the bird was put there by someone...” “No matter how a fish swims, it can never meet any of its kind, which only means that the fish is kept in a fish tank...” “Yes, we are the birds in the forest and the fish in the tank.” “Yes, the world we live in is virtual!”
