The female lead is different in every world. These are episodic stories that can be read as short fiction. Some parts may be original, others may be crossovers, and the characters might go out of character. The plot may, or may very well, definitely go off the rails, so please go easy on me. No hate, I'm scared.
OOC. Some worlds have couples, others don't.
The current lineup:
Original female lead × Death's Game / no couple
Original female lead × Harry Potter / paired with Cedric
Original female lead × Dashing Youth / has a System / sort of a couple
Original female lead × My Journey to You / no couple / has a System
The order of appearances may vary.
