Fudanshi-kun No Honey Days
First is boy and hairdresser, second is student (crossdressing as his twin sister) and teacher, third is the four of them together--this is the one where the brothers lick cum off each other's faces, fifth is them talking about marriage. Six is friends to lovers (with the incubus turning one into half-female and UNF the last part with him asking his bf to get him pregnant), then the incubus and a different teacher.
Himitsu ni shiro yo!!
Adorable loner cross-dresser ends up with quiet gay fellow student. Also, cross-dresser is total tsundere but not so overdone that I can't get past it. Whee.
Secret (ARAYA Miki)
Fun story about a teacher and his cross-dressing student lover. Teacher's kind of an idiot, but still a good story. 190 pages
Ichizude Karen Na Ore-sama
Hana Ni Kuchizuke
I enjoyed it. The characters are a bit rough and I like that they're real. They both screw up and have to fix it.
Tenkousei (nakamura Asumiko)
Not sure if I'd say HEA, but the story was good. I liked the relationship between the students. The sex was hot and I liked the other two students. This mangaka's art is... interesting. Still not sure about it. But otherwise, it's a great manga.
Hana to Ikkun
These two are such idiots, but I loved this one. I love how much they love each other and I love how much Ikkun stuck to his guns. I also loved that Hana didn't blame him for what happened with the kid. Great story. :D
Katappashi Kara Zenbu Koi
That was fun. The friends-to-lovers was great and I loved the way the yakuza one worked out. That third one, though. Tsundere. *sigh* I can deal with it, but it would have been nice if the boss had given up at least a little of that. This mangaka seems to like the tsundere types. not *bad* but take it in bits (don't binge-read their stuff).
Hi Manyuaru Ren Ai
Okay, this was sweet. I felt so bad for the tachi, but I liked that it's so promising at the end. :D
