Jess and Leslie were twins when they were born on March 28th 1999. Three months later their parents got divorced. Leslie is living with the mother and on the other hand Jess is living with his father. Many years have passed and neither parents told their child they had a twin or that they had another parent besides the one that they lived with.
As time went by, Jess and Leslie, coincidentally, both went to the beach on the same day! They met each other and never knew they were related. Finally that day Jess and Leslie were both hanging out on the beach and the parents saw when the kids were playing. That night Jess and Leslie were both told that they are related. Now not only they are friend but they were now siblings.
