[BTS] Heartfelt Devotion

Content warnings for this story (please stop reading if anything makes you uncomfortable):

1. BTS eighth-member premise. Mostly daily life, with a small career storyline.

2. Everyone gets caught in a love-triangle situation. The members may be somewhat out of character, and the writing may have issues.

3. The eighth member is a heroic spirit. Some elements are the author's own additions or revisions. There is a magical energy transfer setting, and a bit of a fantasy vibe. Please don't read if that's not for you.

4. The ending hasn't been decided. The author is still thinking about it too.

5. Feel free to point out bugs. Don't come here just to nitpick. If you don't like it, leave on your own.

Theme: You are the joy of my life.
