Wow Fujii. You might not talk with the people you met anymore. But you did talk. And thats enough of a reason to see them as friends forever. Why? Because they have shaped your experiences. Even if they remember you faintly as a quick passing, you see these quick passings a part of your whole being. The emotions. Interactions. Influences. No matter how small, you appreciate them. That might be the true sigma mindset. You appreciate the totality of your life. God I love this manga.
