น้องสาวแย่งเจ้าบ่าวฉันอีกแล้ว

I am the princess of the Shadow Wolf Clan, bearing the clan’s one‑and‑only healing power. But then, their biological daughter was brought home. To my shock, she stole the prince of the Thunder Wolf Clan—my fiancé. On their wedding night, the two of them whispered and tangled in each other’s arms. Very well. In this second life, I shall grant you two wretched lovers your wish. Every debt you owe me, I will collect every last bit of it.
