Tasogare wa Karera no Jikan

Unbelievably gorgeous, Ritsuto Okumura has always been able charm anyone whether he wants to or not, even to the point of obsession. Although he is the only member of the current Okumura family who possesses this arcane ability, he dresses conservatively, even obscuring his appearance with glasses in an attempt to counteract this strange allure, as it only seems to bring him hardship.

Against his better judgement, Ritsuto uses his charms to help his cousin with a client. The latter then tracks him down at his workplace, completely infatuated with Ritsuto. While wondering how to safely escape from his new stalker, a striking man with long black hair named Luka appears and tells Ritsuto to order his stalker to leave him alone…and he does! Desperate to understand what just happened, Ritsuto follows Luka to his hotel room but instead of explaining, Luka pushes him down and tells him, "I want you….It is your destiny to become mine," and thus begins a darkly erotic tale of unearthly love.
