Aiden Reed

Your story begins in the world of tribes of Beastmen, and you are Riley.
Riley is a deer girl, and at first, her life seems perfect. But her sister is intensely jealous, feeling that Riley always gets the best: status, attention, and the life her sister longs for.
In her first life, her sister's jealousy reaches a terrifying level, leading her to murder Riley. Riley's life ends with her feeling betrayed by the person closest to her.
But the surprise is that Riley is resurrected and goes back to the past, specifically to a very important day called Mate Day; the day on which girls choose their life partner.
And here Riley decides:
This time I will not repeat the mistakes of my past life.
When it comes to choosing husbands, Sister Zoe intervenes and chooses a strong man from the Lion Tribe, who is seen as an ideal, strong, and high-status husband.
Everyone expects Riley to be jealous or to try to take the man away from her.
But Riley, because she knows what will happen in the future, doesn't fight her over it.
Instead, she chooses a man who seems to everyone to be the worst possible choice.
A very weak, poor, and despised man, referred to as a kind of "underground insect" or the weakest beastly man.
Everyone is shocked by her choice.
Even her family didn't understand why she chose this man, but she didn't know that he was the king of dragons and the king of monsters.
But Riley doesn't know that she has chosen the most dangerous man in the world!
The man Riley chose is not weak at all.
He is in fact the legendary King of Dragons, the King of Beasts, and his name is Aiden Reed.
He hides his true identity and disguises himself as a weak man so that no one will know he is the Dragon King. In fact, people didn't even know his true form, so he can live among them undetected.
What's even more remarkable is that the king himself believed that Riley would reject him when she discovered that he looked weak.
But Riley means:
"I don't care if he's weak, I chose him, and he's my partner."
This is where the Dragon King begins to fall in love with her, because she is the first girl to choose him without knowing his strength or status.
He feels that she loved the person himself, not the king within him.
