Grow up, you immature child. How arrogant do you have to be to claim that something you don't agree with is wrong? The OP is allowed to want to MC to get back and play the role. I don't like the story either, not on a character level, but on a lazy writing level, using obvious tropes and stupid excuses to make the plot work.
What an immature child I am, calling someone out for starting an arguement with a strawman!
The OP is also allowed to feel whatever they want as I mentioned you weirdo. Don’t misconstrue my initial statement. But the writing factually was good and there was no need to lie (being wrong).
To then proceed and mention one of the most enjoyable aspects of this manga (his sometimes toxic helpfulness/positivity) but as a negative and when it doesn‘t even apply just to make a point.
And finish it off with blowing everything out of proportion when he himself was rightfully (everyone went above and beyond to make him feel like a background scrub) under the impression that his work was mostly done and that they would be able to hold on without him.
He also missed most of the play but saw her when it counted most to both of them.
Him missing most of it still is the best outcome with what we saw in regards to his mental state. He even was a bit too early tbh.
Reading comprehension.
The "wingman“ was arguably infinitely worse than MC in every way and made no sense writing wise if you want to criticize that aspect.
Hope this child‘s belated reply finds you well dear mature adult. How about you bark up the correct tree next time.
