It’s like he’s aging backwards good for him. The tragedy of him becoming worse at shouji (not a lot worse but he definitely is less focused on it) because he has other things to look forward too but he’s finally accepting that it’s good for him. It’s like the idea/meme of “I’ll lose my sparkle” when you take care of a mental illness. He still enjoys shouji but now it’s not life or death it’s a game he is good at and can talk to friends and mentors about. good god his character development!!!
