Help me find a bl manhwa

I forgot the title ╥﹏╥. There was a scene where the omega escaped frome the alpha, he change his hair color and went to the mountain. I remember that he encountered a wild boar. The alpha hired some men or agents to find the omega. The omega noticed the men, i think he used the wild boar to distract them. The alpha also went to the mountain but the omega was already not in the mountain. And I think the omega then is pregnant.
