what is their age gap??

there's a chapter in their somewhere where it's explain all the information about them but I can't remember what chapter...

Dowon and beom are 6 years apart. I think when it started they were 30 and 24 and now it's 2 years later so 32 and 26. Dojin is 2 years younger than his brother so 30 and his partner taeju is a year older than dowon so 33.

Thank you

thank you very much
