Houtou Musuko to Sewagakari
A carefree son is summoned home after dad gets wind of his grades. He falls for his servant, who has crushed on him for ages. His dad's story: Twenty years after brothers-in-law-to-be fell in love and risked a forbidden affair, they have a chance to be together. Too short, but I would read a hundred chapters about the dad. Both story lines are entertaining, but the dad's -- finally being with the person you've loved for two decades -- really touched me. Honestly, I reread the dad's three chapters probably once a month. That's why this gets five stars. It really resonated, despite not being long or developed. I'd write a novel based on the concept of waiting twenty years to be with the person you loved.
XXX Allergy
A young man with an allergy to rabbits, the one animal he adores, works one hour a day in a shop so he can still visit them AND the super hot guy who runs the place.
Secret XXX
After they fall in love in the rabbit store, Mito and Shouhei continue their romantic adventures, navigating work schedules and parents, and eventually cohabitate. This artist has Scarlet Beriko's gift of infusing intimate scenes with genuine feeling. They were more explicit than hers, but they had the same underlying tenderness. I don't know how to describe it, but not everyone can do it.
Kuro X Koi
Ao has a crush on a man whose son attends the kindergarten where Ao works, but when he discovers the man is his twin brother's boyfriend, he is forced to give up.
Hitorijime no Jouken
A series of one-shots featuring super hot characters, especially the last two.
Kanga na Spoon
Chapters 1-5 are a great love story between longtime friends. Chapter six veers into abusive noncon territory but features an on-page wedding, only the second I can remember seeing (the other in Haru wo Diete Ita). The final chapter is two high school students with mutual crushes.
Daikirai Na Aitsu
A wealthy and grouchy man who has never lived on his own gradually falls for his beautiful housekeeper, an actor who works part time to pay the bills.
Kizutsukenai de ne
After he gets kicked out of his house, Satou moves in with a guy he started dating on a whim, who has no personal possessions and won't talk about his past. TW for some on-page domestic violence. A chief and subordinate fall in love.
Rakuen No Ori
A hot guy with long hair who works for an organization beating people up, I think, ends up in a bizarre relationship with the younger brother of a yakuza boss who can only see from one eye. He likes to choke the long-haired guy during sex, which is freaky at first and then turns into a kink. Super unhealthy relationship involving dubcon and drugging people, but they seem pretty happy about things by the end. I've read chapter 4 before: "Unknown Letters," the yakuza and detective who had been in love in high school and now sleep together in an information exchange. It was sad the second time too. The final story I've also read, which was a 36yo who took in a 15yo after his family died, and then feelings develop. He vows to wait until the kid's 20. It's a little...hm.
