why do i always think that exo D.O kyungsoo will be the perfect son of yongseo couple, they don't look alike too much but they'll make a great family just imagine yonghwa getting  ignored by his quiet son that would be a perfect comedy family AFF. 

they will make many AFF 

like the only heir and a poor girl having a secret son from his family

or a historical fanfic that would be...WONDERFUL

or romantic comedy family

or more kkkkk
