As I said in the previous chapter, it feels like every chapter after the field trip is a cop-out instead of a naturally developing narrative.
The same applies to this ending, it screams "cop-out."
We had an interesting premise with a slut trying to get attention from the one guy that didn't fall for her charms, yet it quickly devolved into romcom tropes without any hook and terrible execution.
It was so interesting when he clearly wasn't interested in her and only focused on himself and his klutzy friend, he was a protagonist with a spine and sense of self respect that we just don't see much of nowadays! But everything was ruined when we got the field trip and he thought "oh, she looks cute when she is unconscious", and from there on out he just had to fall in love with her for absolutely no reason whatsoever!
There's not enough time for a natural relationship to develop here, so their blushing and distancing leading to their eventual closure feel forced and warranted, there is no trace of the protagonist from the first chapter left, not because he grew and developed, but because he changed his personality and goals! The only consistent character here was the klutz girl that keeps flashing everyone, but only because she wasn't a character, just a gag!
This is bad! I give it a 4/10.
Not as bad as Tsuihou Suru Gawa no Hanashi, but it isn't even a dumpster fire like that one, so it doesn't even have the same value as a work you can learn what not to do when writing, this is just a bunch of cop-out chapters stringed together!
