Park Chanyeol came from a family with a good track record serving in the military for Republic Of Korea. His background made him not easy to show emotion and because his family moved a lot, he never really had a 'good friend'.

Byun Baekhyun was actually a smart student but he never liked studying. His parents tried everything to encourage him to study but he was still going to school late everyday and prefered sleeping to listening to the teachers. Baekhyun always said what was in his mind and not afraid to show what he felt towards other people.
