Believe-or-not, this year is already halfway through. Which always means that the semester is over again.

Most of the universties is probably having their final exam, but POSTECH starts their semester 2 weeks earlier than most of the universities, so we are already done with the semester.

How have I been

Thanks for learning from the honorable CTF teams, I was able to participate DEF CON 2025 Final with Cold Fusion. From end of the semester, most of my concentration had been on it.

My GPA was not that bad - actually, got perfect GPA in majoring courses but liberal arts courses were (always had been) terrible. Most frightening thing is - I have to take 6 more liberal arts credits to graduate, but I’ve already taken 18 excessive majoring & extra credits.

Just after the semester, I went to the 1-week trip to Japan (for some anime-things) with my friends, and I hope to write a blog post about it soon.
