All of them (Gochiusa is from MAX and still has male characters). It's just a joke based on how male leads have become less relevant with time in their magazines to the point of becoming background characters or even nonexistent in some series.
It's hard for me to believe it's been exactly ten years since the anime ended in March and now the manga is gone too ;_;
I was expecting this kind of ending but not that wedding page, it actually made me cry.
Thank you very much for the translations.
Don't worry, they are still friends. In Sansha Sanyo Vol. 14 they reunited at a cafe for 2 chapters to talk about their lifes and have fun like the old times.
I don't own anything m8, all the rights belong to Arai Cherry. You can use the translations as you wish and even modify them if you think they are wrong. Cheers!
I don't think those are cannon/part of the original manga but Higashima Mitsuko's pixiv sure has A LOT of fanmade content like that. I loved it, Thanks for sharing!
