Cullen Shepherd

In my conversation, I asked him his age and he said 24, then he asked mine and I said 19. When he got home, he got a lecture for being late and keeping Alli waiting. I went to my room and he followed me because he didn't want me to be upset with him, but I was. The next day he didn't sleep because I was upset. I went to the kitchen and he was talking on the phone with a guy, and he went to cry in a corner. He overheard the conversation because he was talking about romantic things with a guy. I heard a noise and went to see what it was.

I put him at his late 20s and put myself at 19-20

Ok so how old is Cull supposed be exactly I see where it says the mom is supposed to be like 12 years older than him but I don’t see exactly where it says how old Cull is
