It's not like that!ヽ(`Д´)ﾉ At the time Chase was already in the rut and not thinking straight while coming into the hotel and he accidentally went Josh room or something like that. Basically he being not fully conscious and a cloud of pheromones came directly to an Omega and directly induced his heat (cause he didn't yet start taking the super strong kinda illegal suppressant he's taking now). And now both of them are not fully conscious and they just went at it. ╮(￣▽￣)╭ Sure the fact that Josh liked his face is the reason he didn't desperately resist it, but it's not like he's the one attacking him. After all he's actually always been more into women than men, so if not for the face he would probably punch him... ┑(￣Д ￣)┍ I feel like it was explained way better in the novel...(￣∇￣")
