THANK YOU!!! I was going to reply to this too, people are starting to irritate me under this comment thread, they’re so desperate now that Chase literally JUST found out Joshua is omega they are so desperate for him to put things together like it’s so easy. Like are ya’ll forgetting the plot? The fact they haven’t properly communicated about any of this yet? The fact that Joshua also played part in covering up things so Chase won’t know he was an omega in the first place or even pregnant with their child? Like they’re forgetting the plot and what Chase has been through already and how he doesn’t even remember how he slept with Joshua in the first place. They’re rushing things all of a sudden and forgetting everything that has actually happened so far in this manhwa.
Like Chase can be dense sometimes but let’s not act like those subtle hints are going to instantly give away Joshua’s situation/ the fact they have a child together (without any proper communication/ content involved.)

Chace knows Josh gave birth to Pete? because if he does and Josh confirmed that he only slept with women, and Chace is his first, which means Pete is his son.
But all the Grayson siblings share the same brain cell so he probably won't this about this too much.
