Not just a letter

Once outside, Hina took a closer look at the envelope. The paper was old and yellowed, and as she took the time, she realized the envelope was heavy. There wasn’t just a letter inside. It intrigued her, and she wanted to see what was inside, but when she turned the envelope around, she noticed a wax seal. Hina sighed as she realized there was no way for her to open it without it being noticed.
