Angel is not a "normal" character, he is also a dominant omega. He has no problems kissing strangers. He kissed Koi (Connor Niles), who also is another dominant omega, when running into each other the first time.
Angel was kidnapped, sold and abused by 5 dominant alphas ( it needs 5 to controle a dominant omega, because they can use their pheromones against dominant alphas). Forced to bear them offspring, was not allowed to have contact to his children. When he tried to run away they physically hurt him.
So it's not surprising that Angel is not acting "normal".
And Keith is aware of it, so probably just goes along.
God, I didnt remember this being dogshit, I came here to recall everything a I read to go to Kiss me if you can. Did I read to fast or does Keith literally kiss his fucking FATHER on the mouth??
