At first glance, I didn't much pay attention to Sky. But then the story focused its attention on him and you couldn't help but feel sorry and want to comfort him, once his past was revealed.
And Ken. His horrible past and horrendous experiences made me like him instantly. It was amazing to observe his will to go on and evolve beyond the traumatic events that marked his early years in life. I was equally interested in his curious attempts at adjusting to society and I so longed to read more about it. And hopefully, about growing feelings between him and Jin.
Mark. There was so much despair in him. Such torn devotion between his love for Dylan and attraction to Jen. Despite Jen's destructive nature, he was unable to completely pull away.
I could not fully understand their abilities. Each character had a brief moment in the spotlight. Definitely not enough to completely portray them but enough to pique my interest. Enough to make me care for each. So just for leaving me hanging... 4.5 stars.
