The reaction to this story is kinda interesting and not at all what I expected.
From my perspective, it's a story about a guy who was trying to "stretch beyond his means" (in his own mind) and finally cracked and started to hate himself and walk a self-destructive path of malaise.
But along the way there were people who always genuinely cared about him. His sister who would always bicker with him but never meant it seriously, it's just the awkward way different gendered siblings connect (at least to her). She was devastated when she realized that her brother had taken her words seriously.
The girl he had been bugging, maybe she doesn't like him romantically but she genuinely values him as a friend. He himself is the one who started this "game" of "harassing her" and set the tone from the beginning of their relationship. He never seemed that serious about dating her because he was always asking her out in a joking manner. Suddenly he gets serious and asks her out and she's caught out of left-field. Regardless of her romantic interest in him, she wants him in her life.
The girl's best friend also cares about him, that part is straight-forward.
Even the ikemen that the MC seems to dislike is always trying to talk to the MC and bring him into the conversation.
It's like a story of an MC who was always self-loathing and he played the fool, "reaching beyond his lot in life" until he eventually gave up. But all along, no one looked down on him more than he did. The people he compared himself to never looked down on him. His average face and "average personality" never seemed to actually lower other people's impressions of him.
His self-loathing twists his perception of the world. No one else even dislikes him, at most they are just immature and awkward around a guy who frankly sets up those types of relationships.
But the rest of the comments seem to think that everyone else around him is pretty terrible so maybe I'm tripping??
