What an idiot. I know he has self steem issues. Self-confidence issues. Intelligence issues. The balls he had to deal with annoying brat went poof to another dimension in the one time he actually needed them to get himslef a girlfriend.
I don't blame him for not realizing that S-girl was talking about herself and her feeling about him. Because being able to read those types of meanings is a skill he doesn't have.
So close, so f'kin close. MC almost had a breakthrough, but he gave up right before the finish line. Maybe Sumi will become Deus ex Machina and save this shitshow of a relationship despite MC-kun's best efforts to go nowhere in life.
