MC had ZERO talent in streaming for "unknown" reasons but was later found out to be because he was mistaken for some click baiter who is lying about being a talented high schooler for dungeon exploration.

Then was even threatened to show his ID to "prove" he wasn't lying. Of course, the MC didn't BECAUSE he was trying to protect his privacy and indirectly affecting his family. This was a point the author might have wanted to emphasize regarding what type of personality the MC has. He was portraying a considerate and kind MC. Which I don't know why that commenter didn't input this which can be seen they probably skipped or skimmed through the novel.

But later on because of that accusation, MC went into low self esteem mode and even thought about quitting as a streamer. So he casually decided to watch other dungeon streamers which happened to be his classmate, the candidate heroine as I nicknamed her to be.

My second point, after learning his classmate was in danger he made a rash decision to save a life. Yes ladies and gentlemen reading this comment, to save a life

.. Why is that? Oh, I don't know. Isn't it obvious because author is trying to blatantly express what personality our MC has. Yes, good job A+ for guessing. To emphasize it more, our MC didn't even go love struck on the girl but genuinely acted as a normal raised gentleman escorting the girl out the dungeon for safety. This was disregarding his intentions to keep private but he also didn't do it intentionally since narrator notated that the camera dropped by candidate heroine's assistant was left running and stayed on. I directly exposing the MC, starting his path to fame. This created the "diamond in a rough" phrase which the viewers in the story late find out as it goes by.

I mentioned this in the beginning but MC has no common sense at all. This led to his ignorance. He did SOLO streaming for 2 years straight (mentioned in one of the chapters that he started streaming for two years since he's a 2nd year, I'm assuming he started in 1st year of high school.) during that two years he wasn't in a group and even when he found his classmate in trouble IN THE SAME DUNGEON MC indirectly gave out info that it's not often you run into other explorers since it's a huge a*s dungeon I'm guessing. Anyways, he basically didn't hang out with others or go into a group leading to no strength or knowledge comparison. MC was just s*upidly talented in fighting as an explorer, what you call natural born genius. Even if he watched other explorers, bro has major self esteem issues due to his poor viewership so he tends to overestimate the strength of the ones he watch who HAVE MORE viewers than his pitiful self. That's already a clear explanation as to why bro is so damn clueless.

this is just one of the author's build up emphasizing the MC's broke ass. He later gets gifted with a budget friendly equipment from a viewer regarding this.
