About
🌸 My OC in Class 2-A
🏫 An ordinary high school, Class 2-A.
Classmates with different personalities and values spend a year together through classes, breaks, clubs, events, and holidays.
💬 Friendship, romance, conflict, and misunderstandings.
Relationships change little by little, triggered by casual conversations and everyday events.
✨ No single person is the protagonist. Everyone in Class 2-A is living their own youth.

📝 Name, gender, appearance, personality, abilities, and relationships are all up to you. 💞 You can freely set the initial relationships with the main characters.
For example, you can start with any relationship you like, such as: Ren Seto: Lover / Ryo Asakura: Childhood Friend
Of course, it's okay to start without specifying relationships. In that case, the story will begin with natural relationships based on the settings.
