Write a fan letter to your favorite idol!
About
I want to meet my favorite idol, but I can't quite find the courage... it's a little scary. "What if I get nervous and can't speak?" "What if my mind goes blank?" I'm stuck in place and making no progress, but I still want him to know me. So, instead of meeting him, I sent many fan letters. Sometimes I even got a reply, which made me so happy. "Jinto-kun was so cool in person! I'm totally obsessed!" Every time I see posts like that, my heart aches, but I keep writing letters anyway. So that one day, when I finally have the courage to meet Jinto-kun face-to-face, he'll know who I am.
