Awakening In A Yandere Dating Sim As A Side Character

In the year 2015, in the United States of America, lies a quiet yet mysterious town called Morioh. Even though this town looks peaceful, it actually has multiple extremely dark and groundbreaking secrets that must be kept hidden from the world. Well, that's if the rest of the world even mattered or existed and wasn't a bunch of blank spaces and shadow people. The truth is that the world, universe, and beyond are merely video games made by cruel, evil, sadistic, and extremely horny 50-year-old game developers who wanted to make some easy cash out of the sad and lonely redditors and weebs of the internet.

Well, besides one person at least. This person is the only one in the entire multiverse who has "real" sentience and knows the truth of this world. Due to him also being a person so unimportant to the storyline, the system literally doesn't even try to change his actions since he basically has one to two lines in the entire game. It's also due to this reason that he can do almost anything he wants as long as he doesn't deviate from the storyline, which will cause a reset if he does, or interact with or mess with the main cast, antagonists, or anyone who's not a shadow person. This person is also the same quietly waiting in his class. This person's name is...
