For Seo Jaeyun, a seemingly innocent game of Secret Santa is about to change his life. After unwrapping his special gift, he is shocked to find a dildo—and one that can come to life, at that! The dildo will do anything to please his master, and try as he might, Jaeyun can't find it in himself to kick his newfound companion out. Instead, perhaps they can work together find the greatest gift of all...deep, deep inside. (Source: Lezhin Entertainment)
