General details:

-Art reminds me a lot of Harumi Chihiro's style: https://www.mangaupdates.com/authors.html?id=4933 in that the female lead is drawn with big boobs and a curvy body...
-There's more than two volumes, around 200 pages each
-It's a Japanese hentai/adult manga published in a magazine, NOT doujinshi, but it's not pure fapping material, as it's porn with plot
-It's strictly straight, MxF, no LGBT themes
-No loli/shota/underage, only adults engaging in sex
-I recall one of the volume covers having a red-haired woman either naked or skimpily dressed on a white background
-I'd classify it as drama/romance with porn and plot intersecting

What I remember about the plot:
-Male office worker(?) crossdresses as a woman and manages to attract a bishoujo heroine
-The heroine falls for the crossdressing male when he's crossdressing as female (she falls for his female version)
-The male crossdressing hero and heroine have sex, at one point the hero is dressed as a woman having sex with the heroine
-As the manga progresses, the male hero meets the heroine's ex-lover(?), who is your typical ikemen, with dyed blonde hair. She has sex with this guy behind the male hero's back(?)

Now, about the heroine... I can't remember her hair color. I remember distinctly in later volumes that her her is red (when she's having sex with the ex-lover), but I also remember her hair being black when she's having sex with the hero. I'm pretty sure it's red throughout, but it's been a while since I came across this series.

I originally found this series on a Chinese manga website, flipped through some pages, found it cool, and promptly forgot about it till now. I think the series has been scanlated, but my only lead in finding it is the Harumi Chihiro-esque artstyle. It's on the border of josei and seinen. Please help me find this, guys.

Sounds like Matsutou Tomoki's The Rumored Hostess-kun? However, in that series, there's eventually another guy who shows up and crossdresses, and then that guy becomes gay for the MC.

Could also be something by Locon, but that guy only makes gay series.

Unfortunately, that's not it. Thanks for the response though. The art doesn't match. From what I remember in the manga, there were no gay scenes. I guess you could call the scenes where the hero was dressed as a girl while kissing the heroine gay, but we know from the beginning that he's crossdressing.

I remember one scene where he puts on his female wig, starts having sex with the heroine and it comes off. And that's the reveal that the hero is crossdressing--the heroine is horrified and confronts him.

You know, maybe the manga never was scanlated. I thought it was, but after having gone through every ecchi/hentai list I can find on the English side of the Internet, I still can't find it.
