Seto No Omise No Okyakusama
Man goes to a town to meet his unrequited love, an older (slightly older) man who has moved to another town and bakes delicious treats. The man tries to convince the person he loves to come back to town, only to realize the next day (as he's leaving, and not on purpose) the reason why the other man stays. ~Chapter 1
Neko x Neko
A couple who has been going out for three years decides to reverse when the uke becomes big enough to be the seme. The seme, who identifies as straight, was reluctant but wanted to give it a try. Within the tension before they have sex as a reversible couple, they are in the midst of building/renovating a cafe -- someone hired them as an architecture student and a full-time contractor. They end up talking about their feelings regarding sex, each other, and the development of their relationship. I would say that the manga is well-done. Edit: They're a true verse couple. They actually switch, even when the first 'uke' gets his 'seme' physique and tops the original 'seme.' ~Chapter 5.5
Like a Sugar
Second-year high schooler Hayakawa ends up running into 'Mad-dog' third year Shima. Shima ends up stopping by this kid's classroom and (after a long relationship of him just eating the Hayakawa's sweets) asks him how to make some of the sweets. Slowly but surely, they fall for each other. Side note: you know, one of the few manga that I've gotten my guess on who the seme and the uke is wrong (that's how typical and one-dimensionally sexist that most yaoi mangas are...(I can guess by the way most power dynamics are typically socialized/revered)) ~Chapter 5.5
Gokusen
A boy and his high school teacher get into shenanigans because of past and present ties to the teacher's yakuza history -- that history being that the teacher is heir to her yakuza syndicate's throne. Because of this interesting upbringing, the teacher is well suited to this school of delinquents, whether the students initially know it or not. Boy, are they in for a surprise... ~Chapter 'Gokusen Halloween Special'
