Yan Yi is an exceptional omega, possessing a rare tier-3 gland cell. But when it comes to compatibility, numbers are everything, and his compatibility with the alpha Lu Shangjin is too low a percentage. Eventually bored with Yan, the alpha removes his mark and breaks their bond, but Yan Yi never stops loving him. So when Shangjin finds an omega with more compatible glands, the choice to undergo a risky transplant surgery seems obvious, but will it be enough to restore the love they once shared?(Source: Tapas)
