Star necklace

The Crown prince Yeol looked down from within his private room to where his future wife stood. He could not truly understand this feeling roaring through his hearts, mind and veins. 

The crown prince, Yeol, is aware that his future wife will be shared between his twin, this is something done when males had siblings who shared the same egg sack. 

That is because what should have been one soul is split in two separated by the two identical but separate bodies. The twins themselves are then forced to share their mates because of this, to both prolong their life span and ensure that they could reproduce young. The seed from one male will be a catalyst to help the female open for the male who would then deliver the next set of seeds to merge with the first and allow the seeds to fertilise the egg or eggs targeted.
