Marinette & Adrien used to be best friends, Marinette always wanted to be a fashion designer, one day, when She was 16 & he was 17, she got a call from someone saying, she got her own fashion design company but it was in London.. she didn't want to take it because she didn't want to leave him but he made her do it & a couple years later he was watching TV & there was a ad on 'Mari's designs' & it said a phone number to order clothing and he decided he could phone that number to talk to her.
