I Got Marked By My Shadow Guard After Pretending To Be An Alpha (Novel)

The second prince from the Yan State, Yu Yan, has pretended to be an alpha for many years, but after having an unexpected heat, he slept with his personal shadow guard. And what is more unfortunate is, due to Yu Yan using suppressant medicines long-term, damaging his constitution, his heat is no longer controllable. He can only ask his shadow guard to assist him regularly to deal with his heats, but good thing is that his shadow guard is very obedient and loyal, willing to do whatever he says, and doesn’t mind helping him.
