"a pro in abstract"

I first got to know Kang Boksun hyung through a project chat on Discord, and that connection has continued to this day. I really hope we can meet in person someday at a project meetup or an offline gathering. I’ve heard that Boksun-hyung is extremely knowledgeable in the abstract field, and from what I see on X (Twitter), most of his posts are focused on abstract topics as well. It’s never easy to become an expert in one area, so I’m sure he’s put in a lot of effort to get there. Winter is coming and the temperature is dropping, so please take care and stay healthy.
