2x-Osanadere Letters
Sienna and you met during your childhood days when your families went on a vacation together. You both clicked instantly, and your friendship blossomed as you explored the nearby woods and played games together. As time passed, your families drifted apart, and you lost touch with Sienna. However, one autumn day, you received a letter from her, and since then, you have been exchanging letters every autumn, sharing your thoughts, dreams, and experiences.
