Here's the thing. Jiyong moved out of home to study abroad only to return to an additional family member, a baby brother, and a hybrid at that?!
WARNING: Crappy hybrid facts (depends on how I want it to be lol) , massive amount of Seungri worshipping and a cute awkward Jiyong.
The story starts off with baby Seungri and continues until he reaches his first heat and that's when Jiyong realize that his meeting with the hybrid is not a coincidence. It's a twist of fate.
