よろしく・マスター (Yoroshiku Masutā / Sweet Rein]

In this compact three-issue manga series from Hakusensha (2005–2009), a young woman's life takes a magical turn when she becomes the master of a reindeer who transforms into a handsome man—a bond that comes with a surprising seasonal duty. Written and illustrated by Sakura Tsukuba, Yoroshiku Masutā (also known as Sweet Rein) is a charming, lightly fantastical romance that stands out for its brief, focused storytelling and its warm blend of everyday life with gentle supernatural elements.
