Shiawase ni Michita Yoru no Niwa

Noah, a beautiful Alpha, is supposed to marry a female Alpha in order to keep the bloodline pure and is therefore forbidden to have contact to Omegas. One day he meets Hajime, a male Alpha just like himself, and falls in love with him at first sight. Though he knows their love has no future, they start a relationship. Is there still hope for a happy end or does Noah have to marry a female Alpha like his parents do wish for him? Note: Includes the one-shot "Nicholas" (ニコラス).
