Grayson's younger brother.. Chase Miller. He's a movie star and josh worked as a bodyguard for him. Every single Alpha in this manhwa is a piece of shit who treat their partners like trash. Josh had a one night stand with his boss when he suddenly had a heat. Chase was in rut at that time. Shitty luck for josh. As you know josh was a beta before but turned into an omega because of too much exposure to alpha pheromones, just like yeonwoo. So that single one night stand got him pregnant and chase didn't remember anything. Worried about his unborn baby josh resigned from there. There's a separate story about these two. You'll be just as frustrated and angry with chase as you were with keith. These shitty alpha's don't change unless they fall in love fr sheeesh ( ̄へ ̄)
love how everyone hates that lomg haired boy who took spence's pudding
