Oh, there are quite a few in my lists. Although the genre is mainly Shoujo... Kkk.
*
Nemurenu Yoru wa Knock Shite - Old school yet by times funny, because the female lead gives of a rather "nerdy guy" feel.
*
Ookamitachi no Tengoku - Ch. 2: Handsome Girl is Yours! All in all this collection was a nice read and worth it's short while.
*
Otomegokoro - Almost a classic in this category, but in my eyes is the male lead till the end somewhat wishy-washy and ooc.
*
S.P.Y. ... was okay, even though mainly because of the male counterpart's looks. Lol.
*
Sugars (YAMAMORI Mika) - THis one is definitely one of my favourite collections and I highly recommend the whole thing, but especially chapter 1 and 6. ^^
*
Sugar Addiction - A manhwa, with all the fun points, but also all the weaknesses, yet I finished it and thought the characters have made me smile every now and then.
*
Venus Kisoukyoku - Another classic, where in the beginning the genders seem switched and the female lead is pretty likeable till the end.
*
You're So Cool - Honestly, this manhwa made me crack laughing in between and the characters really keep their image.
*
Yumenara Samenaide - Ch. 3 includes your typical switched gender setting.
*
Obaka-chan, Koikatariki - Ongoing and sometimes just hilarious twists in the storyline, which struggle between fun and randomness.
*
I-Revo - Not sure, because it's been a while, at least the tag says so and the drawing style got me back then.
* And, of course
Yanki-kun to Megane-chan. The female main character definitely has the same aura as the one from
Oresama Teacher, but the romantic subplot seems more focused in this storyline.
There are more, but that's it for now. Not very detailed, but hopefully there will be something picking your interest. ^^
