Mujihi Na Otoko
Volume 6: Mujihi na Otoko "Merciless Man" in Sakuragi Mei's Warui Series. Isolated at college by rumours of his invincible homosexual magnetism, Nanao Shirahane is irresistibly drawn to Kuon Aikawa, another student whose nature is to fiercely attach to a partner and who, thus, despises Nanao, even when he starts to notice that Nanao's behaviour doesn't correspond with the person he is said to be. Mix in a professor who uses Nanao's loneliness, the result of those rumours, to advance his own agenda and you have a lively, and surprisingly emotionally wrenching story by Sakuragai Mei — definitely the best of her Warui series.
