MTL - Say Yes To Making Bad Games, What the Hell is Titanfall? - Chapter 102 Real Cooking Game

Five years ago, Gu Jiayu, who climbed out of the mountain nest, entered the entertainment circle in order to cultivate, and in order to overcome the shortcomings of emotional gaps, he used an excellent acting skill to hook up a Chinese “little nobleman” abroad. After a month of falling in love and feeling love, he ran away with guilty conscience after the other party proposed marriage.

Five years later, Gu Yingdi had become popular all over the country, but he had a four-year-old son beside him. 

One day, the little handsome guy pointed at the man who took up the entire page in the financial newspaper and said, “Dad, this man looks like me!” Gu Jiayi glanced at the calm, handsome man in a suit and shoes in the newspaper, and asked with a guilty conscience, “He has an onion head, and his body is black and black like the top post. Are you sure you look like him?” That night, “Top Door Post” came to the door … Gu Jiayu, “My son, hide your tail!”

Kujo Yuuri, who had been playing Elysia Online, finally changed her occupation to the sage of her desire. Then, she was asked whether to go to the true Elyasia or not and selected [Yes], and somehow went to another world. Furthermore, she became a small child.

The small sage Yuuri and her companions’ love and adventure fantasy.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…
