What scenes would you want in a BL book?

I need some scenes to put in my book "Soulmate for Two." It's a romance book. Here's the decription:

When groups of children get kidnapped and taken to an experimental institute for having supernatural abilities and being half human and half other, read to find out when the main character, Aaron, finds himself in an unlikely love triangle. Is everyone lying to him? What will happen to him? (BL)
