Dear Tanjiro,
Now that you have been gone for a few months, I have noticed that I have some different feelings for you than I had before and it scares me since I have never felt this before.
I'm actually not going to talk to Mom or Big Brother since I don't want them to think that I am weird in the feeling department, or that something is wrong with me so that they will send me away.
Come visit soon. I miss you very much, almost so it hurts.
