Hello, does anyone know the title of this manga, it's omegaverse and from what I remembered they are fated pairs. They are both actors, filming a movie together about lovers who are alpha and omega. I remembered that the pairing scene was the omega having a painted flower on his neck. And during one scene, omega went to a heat. If you can help me, thank you in advance huhu.
