Thankies for the scan.
spoilery mini-review:
Meh >_> Kinda lacked substance, durrrp sex hurrrp ye'r a man plus the parody like atmosphere and start aka meh writing. It wasn't thaaaaaat bad, 2/5.
I'm almost certain that "When I woke up, I became a girl' disease" is bad translation which makes the situation hilarious at first, but
quickly feels dreadful and dire with instant sympathy for the formerly male protagonist with how it realistically instigates the background characters of male to either mock or sexually harass him for sex, with the females categorizing as a disgusting pervert for now having the ability to coexist as a girl with them.
I'm straight, so I don't have any personal care or attachment to homosexuality or change of sex, but it's interesting to see a One-Shot implement realistic factors to the cliche genderswap.
It's fast paced but in its length it
properly presents the girlfriend, her brother/his* friend protecting him and the difficulty of the couple dealing with their new situation, of which as a man at heart he stays true to his love for her and they stay as a couple.
... I've read very few genderswap manga but grew disinterested in them over time even though some could be very good. ... I don't think many go with this realistic approach though, at least not so harshly. If it's present it's usually short-lived.
