Seungri refused to grow up. He wanted to stay as a boy forever. Even as his body grew and ages, he remained his childish 15 years old self. Yes, he was a typical example of the peter pan syndrome. The boy who refuses to grow up. 

Jiyong was overbearing to many people. He was often described as being possessive and clingy. He loves to care and dote on someone, devoting a hundred percent of himself on that person. His devotion suffocates many of his ex girlfriends. He was the perfect man to portray the Wendy's syndrome. The man who is obsess with someone needing him. 

They say opposite attracts. Seungri and Jiyong are Yin and Yang. They complete each other.
