From Fantagraphics:
A DECADE-SPANNING JOURNEY INTO DARKNESS
Even as butterflies ominously proliferate in town, the rumor of a mysterious creature lurking in the tunnel behind the school spreads among the children. When the body of Arié Kimura's mother is found by this tunnel's entrance, next to apparently human traces, the legend seems to be confirmed. Is the end of the world coming? In order to appease the wrath of the beast, the children decide to offer it a sacrifice: The unfortunate Arié, whom they believe to be the cause of the curse, is shoved into a well that leads to the Nijigahara tunnel — an act that in turns pushes Komatsuzaki, the budding thug who has carried a torch for Arié for a while already, entirely over the edge.
But this is only the beginning of the complex, challenging, obliquely told Nijigahara Holograph, which takes place in two separate timelines and involves the suicidal Suzuki; Higure, his stalkerish would-be girlfriend; and their teacher Miss Sakaki, whose heavily bandaged face remains a mystery; and many more — brothers, sisters, parents, co-workers, teachers, aggressors and victims who are all inextricably linked to one another and all will eventually — ten years later — have to live with what they've done or suffered through.

From The Pink Panzer:

Set in New York in the late 1980s, Partners follows the lives of six close friends who also happen to be leathermen. The manga depicts their relationships -- both sexual and emotional -- with unabashed honesty. While the story practically explodes off the page with a continuous, unremitting and glorious parade of smut, it isn't "meaningless sex" -- these are committed couples in full-time relationships, where pleasure and pain are natural expressions of affection for one another.

The six friends that star in this manga are split up into three pairs. The main pair consists of Marlon and Doug, around whose relationship the manga revolves. Marlon, a high-flying executive, plays sub and devoted masochist to the beautifully dominant Doug. Doug is, interestingly enough, a janitor at the very company Marlon directs; during the average workday, they barely even make eye-contact. The contrast between their private and public lives is as stark as it is lovely. The other couples also feature in major roles, and what we end up with is an intimate and moving glimpse at an otherwise unconventional lifestyle.

For both Wakakusa and Yamada, their emotional awakening fosters an unlikely friendship between the two battered souls.
