This MC is the single most annoying self pitying repetitive beta bitch I ever saw. Seriously. The writing irks the shit out of me so far, even though the initial premise seems like something sorta interesting.
I'm only at the restaurant part but already want to quit due to his every second sentence being like this: "Oh I'm so sorry, I'm so so sorry, I'm such a bad son/friend, I regret it so so much please forgive me, I'm so sorry"
Like seriously, he's sorry, we fucking get it, you don't have to bring it up in every second sentence you put into his mouth. This and the repetitiveness of certain words from sentence to sentence. "We're friends. It's important to be friends. Friendship is great. I hope we can keep the friendship. We're really good friends."
I'm not sure why decided to go with this style of writing, but it's annoying and ruins the experience. You don't have to emphasise on the same thing every goddamn chance you have, overdoing it won't make the plot stronger but weaker.
