There’s Absolutely No Problem With The Magic Cards I Made! - Chapter 128: Dekan, Be A Human

On the will left behind by the 14 year old suicide victim K:

“Taku Sugawara is the devil. Nobody should believe his words.”

Growing up in poverty, Sunny never expected anything good from life. However, even he did not anticipate being chosen by the Nightmare Spell and becoming one of the Awakened - an elite group of people gifted with supernatural powers. Transported into a ruined magical world, he found himself facing against terrible monsters - and other Awakened - in a deadly battle of survival.
What's worse, the divine power he received happened to possess a small, but potentially fatal side effect...

On her wedding day, she was humiliated; her status as the legitimate wife was instantly changed into that of a concubine.

“wh***! Marrying you is my life’s shame!” These were the hurtful words that came from her childhood sweetheart, now husband.

….

Jiejie, jiejie, thank you for your sacrifice. Jiejie, if you’re kind then go. Meimei will replace you and take good care of your husband, to help you enjoy the blessings that you are unable to enjoy!” these words spat out by her smiling cousin made her whole body feel cold.

….

“You are shameless! There is no need to say anything! From now on, our Shen family will not have you as our daughter! Someone! Throw out this shameless woman!” These were her relatives?

…

Becoming the target of criticisms, and being submerged in a small lake, she realized that all of this was the result of another person’s scheme – but it was already too late!

…

Instead of dying, she went back to the past, back to where both feelings were still alive and were loving towards each other; back to when she was not yet an orphan but the doted on Di daughter of the Shen family.

No matter what, in this life, she would never allow anyone to hurt the people she loved. And those people who harmed her in the previous life, she would make them pay the price!

Yu Youyao had a nightmare. In her dream, she was married to the Marquis’ son, Song Mingzhao, and had become a mere medicine-human for her third sister, Yu Jianjia. After having blood extracted from her heart for three years, Yu Youyao’s life was nearing its end, so her wrist was slit and she died just like that.

Upon waking up, her heart thumped wildly and she decided to choose the first man she saw to escape that tragic fate. Thus, she clung onto the leg of her maternal cousin who had come all the way from the You Kingdom. “Cousin, I’ll be good to you for the rest of my life.”

Zhou Linghuai looked at the girl nestled in his arms. She had a lovely face and puppy eyes. Despite his usual ruthlessness, he suddenly found himself unable to reject her. And so, he became Yu Youyao’s protector, helping her to take revenge on those who bullied her, fend off the schemes of others, and reject all of her suitors. He even helped her attain glory and magnificence.

Once Yu Youyao reached adulthood, events started to progress according to her dream. The Marquis’s son, Song Mingzhao, had indeed come to request for her hand in marriage. However, Zhou Linghuai pressed Yu Youyao against the wall and said in a low voice, “You’re mine. You can’t marry anyone else!”
