Mattheo Riddle doesnt regret anything in his life. Until he returns to London after 5 years and sees a life he passed up. A life with Y/N he didnt know he wanted but clearly missed out on. And Draco is only trying to protect his family. Y/N and her daughter has been burned by Mattheo before, and he would be damned if it was going to happen again. Things are different. Everyone moved on...except Mattheo wants to fix things, be apart of a childs life he wanted nothing to do with in the first place, and he was hoping deep down Y/N would give him another chance. Even though he was engaged, even though he didnt want their child 5 years ago, and even though she was married to his 'former' best friend.
