I really cannot grasp how old Haebom is like?? HOW OLD EXACTLY IS HE???

I don't know if this is a rhetorical question, and if it is i'm sorry.... but in s1 creator's it says haebom is 36

The answer was literally given in the chapter. He was 30 in the picture with his ex and he explained their relationship was 6 years ago. 30+6???

Harbor is 36 and Sung is 28. Even though it's written as 30 but in chapter 4 or 5 it's written as 28. Even in the creators notes Sung is 28 making them having an 8 year age gap.
