The reasons include:
- Magical-Color-Changing Hair: red in some lights, blond when sun-bleached, brown when short.
- Mysterious Past that he rarely talks about to outsiders.
- Scottish, Irish, and Queen's English accents, mix-'n'-match as he desires.
- Categorically refuses to believe that he's attractive.
- Dances well, claims to not know how to dance.
- Past Tragic Love.
- Steel-blue/grey eyes that are hard and cold and remote most of the time, but soft and warm much of the time around close friends.
- Immediately became a close friend of Our Heroine.
- Rescued Our Heroine from a fate worse than or possibly equal to death.
He is so, so a Gary Stu.
