Does anyone remember how old beomjoon is? I swear I read it but I completely forgot

I'm pretty sure he's in his early yo middle thirties

Ah I was hoping to find his exact age because I finished reading the other manhwa in this series (In pursuit of lust) and his younger brother was 32 there I think. So technically beomjoon should be atleast a year older. But I saw some people mention he's 31? I'm kinda confused about the timeline

Just finished the series, they have an 11 year age gap if that helps idk specifics after that

So he's 31. Thanks!
