I like to think that a lot of the comments here reflect the common sexism that occurs, and that the story in question is an attempt to make a story that would go well in a "shoujo" (romantic comedy) for a "shounen" universe (where it's more It is common to see men brushing each other to see who is stronger...).
In fact, I agree that the story has a lot of script flaws - the basis of the story should be the "body swap", but when the author revealed the swap for one of the secondary characters and the story took more traction in interactions and feelings among such, this demonstrated that the story itself was more about relationships; the "body swap" is just a comical part to draw attention to the story and give it some traction when needed.
Raika's entry tried to touch on the "body swap" issue a little - I honestly thought that the character was probably the one who told Lemon to lie to Sunao about "the three guys" when she was young. Raika has been in love with Lemon since she was young, and after listening to Sunao's conversation with Suzuka, she decided to try to tease Sunao again because she sees him as an obstacle to trying to get closer to Lemon.
And in fact, I also feel a certain confusion about who Sunao is in love with - whether it's Kogohara (who he had started trying around the time of the body swap) or Lemon (now that he's living the day-to-day life of same). But at the same time I have the feeling that the author is forgetting this detail - the day to day exchange of bodies.
I honestly think the story could be better if at least in the first chapters there were a little more details about each person (Sunao and Lemon) during the body swap. The details given end up being punctual, they help a little to understand but not as much as they could. We ended up playing guessing games to understand how they deal with everything.
Perhaps one of the author's flaws is not having gone deeper into "one day of Sunao as Lemon" (and one of "Lemon as Sunao"), to show more how a man would deal with a female body (and vice versa). The most that was done was the beauty contest arc, but the feeling is that it didn't have that much appeal, just Suzuka's confession (who fell in love with Lemon and was dumped right away, but by Sunao :v)
At least Sunao is like any reader of this series - and it's no wonder many people hate the series - as he reflects a lot of the thoughts and feelings of young men out there.
No, the issue is because the very premise just feels too dark and gets in the way.
For instance, he's an actual victim of his girlfriend and the closest person in his life and his childhood friend cheating on him (he doesn't know it's fake) and yet we get none of the trauma or pain he should have suffered. We are seeing no signs of it's existence...
So far, the story is just a basic romcom with body swap added.... but the starting premise isn't actually suited for a romcom....
Change the starting premise and things would be way better.
Yes, you are right, we should see more of the body swap and stuff....the day to day stuff would be valuable.... but we'd expect that coming into later chapters of what we would want to see....
See, so that stuff can wait...
But the very premise just feels to dark and hurtful to just be ignored....
I mean, if you skipped the first chapter and had a summary without the "cheating" thing, this would literally be less heavy and would be way more enjoyable...
Though I feel we would still have issues in the end for problems you mentioned.
That said, you are 100% wrong about this not being a typical shonen.... RomComs are a classic in shonen and this actually isn't very new or special minus the body swap element....
