idk if the lover gender actually is male or female
but i think his gender is probably male since when he looked like girl he said don't i look cute with my new wig
implying he don't look cute without the wig which conclude that he ordinarly look masculine aka male
the girl is probably into trap
Short answer: They have a penis, as indicated in an R-18 thing by the author.
Long answer: From what I can gather, it's just a heterosexual male who likes to get dressed up pretty for his girlfriend, similar to that one hentai series from a couple of years back.
The author/artist is Ponzu Ame: https://twitter.com/ponnzuame/status/1228902604710666240
And for what it's worth, the author's pixiv has shorts with the same characters and uses the tag "女装少年" / "Crossdresser boy" (NSFW): https://www.pixiv.net/en/artworks/74676541
But users here don't seem to care what the author intended ¯\_(ツ)_/¯
@unnes Ponzu Ame is just one of the author names or circle names, you can find works from him/her under Ichigo Ichie, Ponzu Ame, Amezawa Koma going by the twitter profile, depending what kind of work you looking for (Porn, BL, GL, etc, etc), and for that same link you linked, there is the full work i linked in the comments of the chapter, which is free to read until march 15th, NSFW https://www.pixiv.net/fanbox/creator/1203575/post/756722
I feel like more often than not these types of manga (boy crossdresser x girl) are translated and mistaking for Yuri only for the person behind the translation figure out it's not Yuri.
And promptly dropped mid translation
I saw what the person who translated this manga said.. and wow. These the sort of people who bombard your feed with yuri and just annoy you. Guy needs help.
Seems like someone who enjoys cross-dressing, though I'm sure some might interpret it as transgender but not out yet. Based on the author's other works though it seems like someone who enjoys cross-dressing.
Every single character that doesn't say "hey I a boy" while cross-dressing in a manga is represented as gender non-conforming to these people. And wrongly labeled as trans.
i am assuming that this one~shot is getting a regular release is it
i say "assuming" because i cannot read in Japanese
but you can, thank you for the news
that is good news indeed and to answer your question there, yes............ there is one person who is interested in their love story
= that person is me
again, from the bottom of my heart........... "thank you smolbaka"
