Reunion: Hard Die

You will be having a reunion with high school classmates in a few days when you received a handwritten letter. The writer confesses their feelings to you but did not reveal their identity and told you that they're excited to meet you at the reunion. It's been a long time and you can't remember the handwriting. Find out who wrote the letter, determine their sincerity and either reject them or reciprocate their feelings. In the background, a group of escaped convicts are trying to take over your town. Note: Feel free to add more characters.
