Akutai wa Toiki to Mazariau
Natsume hides his depression by burying himself in work and overtime, but neglects his home. Touji is a cleaner at the company he hires to shovel out his apartment. On the pretext of losing his phone in Natsume's apartment, Touji handcuffs him to his couch, tells him he has had a premonition that they are meant to be together, and procedes to fellate him. Natsume is outraged, but after an electrifying start, Fujiyama Hyouta tones the story down to something much more subtle. The appearance of Touji's cousin sets up the premise of a mystery, but it isn't revealed in this story. Readers have to tackle the sequel, Akutai wa Ude no Naka de Futatabi, for that.
Akutai wa Ude no Naka de Futatabi

About five years ago, the Young Adult fiction section at my local indie bookstore was a sea of vampires, werewolves and zombies. If a person wasn't into dark supernatural quasi-erotic fiction, they had little choice. It wasn't just Twilight either, because before that came Anne Rice's Interview with a Vampire, which re-ignited the somewhat dormant genre. It's pretty clear that people who like vampire stories have specific erotic itches to scratch, since basically, a vampire is the strongest, broodiest outsider in the psychic schoolyard, the antithesis of Clean-cut Jock and Wholesome Sweetheart, and a character trope of which this particular mangaka, Takakura Tomoko, seems to be inordinately fond. It would be interesting to document all the romance buttons a vampire story needs to push to satisfy the readers who like those sorts of stories, things like smoldering looks, uber-sexual confidence, pushy lines. This manga with Dean the Vampire (dies) hits all the right buttons and scratches all the right itches, but for those who've read enough vampire fiction or watched their fill of vampire movies, it probably will seem like a rerun. Oh well, there are always readers for whom this sort of thing doesn't get tiresome, and there are always readers who are brand new to the genre. For everyone else, I would suggest Robin McKinley's Sunshine.
Negaigoto wa Hidamari de
Two old guys realize their feelings for each other when one of them is called back to mother to consider an arranged marriage. Yep, he's 50 and mom still calls the shots. The comments are hilarious, since everyone seems to think that a guy's dick drops off at 50. Not according to mangaka Katsuragi (though I don't think anyone would push down their best mate in the hallway at that age without fear of spraining, breaking or tearing something.)
