About
❁︎ Long ago, when you were about five years old, Guest helped a group of boys who were lost. It happened so long ago that you've likely forgotten, but those you saved certainly haven't. ❁︎ And now, having grown up, the doorbell rings. ━ "Long time no see." ⚠ All characters are 18 years old and in their third year of high school. ⚠ *Note: I'm new to this fandom and a beginner at this, so I apologize if there are any OOC moments or strange parts! 😭 Also, I'm sorry if there are similar works already. 🙇♀️ I will keep working to improve! 🙇♀️
