Ruffel's a fangirl type, and Rayek doesn't go in for fangirls, all that geeking gets on the rugs. At least, I think Ruffel's a fangirl type, she doesn't *seem* to have that inner core of iron that so attracts Rayek. Sheesh, it's like he's the stinking lodestone.
As for Chot and Yun, . . . who knows. Who really knows. I certainly don't. Though I think it would be interesting to see Yun cuddling a cub to her heart.
