This Young Master is not Cannon Fodder - Chapter 57: Coincidence?

Theodore Griffith was a master of Reality. He understood the parallel universe in the form of another reality. He was aware that someone’s wish, story, or pure imagination could give birth to a new reality just like his own. Hence, he planned to find the creator of his reality by roaming among the realities. This time, he entered a new reality connected to several other realities. However, what made him certain the most was that this reality was connected to the person who created his reality. He knew that fact because of the ability he gained in this world. He could actually see people’s comments, allowing him to realize that his entire life and reality were born from a story. “Hehe. You have made a mistake in making me realize this. With the readers on my back, I can force you, the author, to make a plot for us to meet.” Theo said while giggling. “That’s why I’m counting on you guys.”

The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.
