While I do think you are perhaps taking a dumb fanservice manga too seriously, I also think "assuming a lot from very little" is often expected of you in media. Like I said, since those 2 pages are all we know of the MC's previous life, it's safe to assume they're an accurate reflection of what the MC's life was indeed like -- namely, that they were an awkward mess with no friends who longed for "intimate female friendship." The rest of the manga is a pretty typical genderbend premise in that the MC is initially resistant to the change but
as time goes on they
become more and more used to
their new identity. The exact gender identities at play in genderbend stories are often pretty ambiguous, I'm just confused why you chose this story to complain about it when it's not really any different from the dozens/hundreds of other genderbend manga out there. There are very few genderbend manga that actually take their premise seriously, so if you're interested in such a thing, I recommend
Until I Become Me and
We Are Former Girls.
Oh, that's an easy one. I choose this one to complain about because of the goddess and the mother.
In most genderbend manga, the cause is an unknown source, like in
Onii-chan Is Done For or
I Am My Wife, is caused by a disease and they have no choice but to adapt, such as in
Until My Best Friend Who Became a Girl One Day Becomes Happy and the one you mentioned,
We are Former Girls, died and were inexplicably genderswapped in reincarnation, like
A Transmigration Vampire would like to take a Nap,
I Don't Really Get It, But It Seems Like I Was Reincarnated In Another World!, and
From The Strongest Dark Knight ♂, Changed Job Into Combat Maid ♀, or changed
without consent by an antagonist who becomes the end goal for the person genderswapped to find and make turn them back, like in
Don't Call Me a Naked Hero in Another World and
Life with an Ordinary Guy Who Reincarnated into a Total Fantasy Knockout (granted, that one's goal is defeating the demon king, not the goddess that changed him, but the point still stands). Here, however, we have a Gyaru Goddess who very much falls into the last category of transforming
without consent and then tells the MC that she's not gonna change back because she has to recharge, as if it's not her problem or her fault.
This would be aggravating enough, but then the mother came in and, immediately after confirming it was her son, threw clothes at him and said he was transferring schools. Not even a single panel shows any remorse from the goddess or any concern or actual support from the mother. Our MC has his entire life upheaval without consent and
nobody cares about his feelings on the matter.
Again, I know that it's just a fanservice comedy series, so it's going to be shallow in its plot at times, but the entire setup for this series is so shallow that it's aggravating how little to no support our main character has. Yes, the argument can be made that the mother is supportive by helping him get into another school, but what he needs is a hell of a lot more than that. Even some of the shallower ecchi manga out there still take even a single panel to address that someone's situation is messed up, even if it gets undermined by a joke the following panel. This one did nothing of the sort and made the goddess and the mother completely abhorrent people whom I'm happy have not returned yet in the series. At least most of the characters introduced since have been fun and nice.
