A lot of people in the world hope to find love someday. Well Marinette is one of them and so was Adrien. They both hoped they'd find someone to love forever. Adrien strongly hoped for that person to be Ladybug who was no wait, who is Marinette. Marinette has always held a special place in his heart, maybe a place more special than the place Ladybug held but he usually ignored his feelings for her due to reasonable reasons.
Marinette, however, wished that person would be Adrien Agreste who is her partner in crime, or rather fighting crime. She always knew that if Adrien hadn't existed, she would've been head over heels for Chat Noir, little did she know if Adrien didn't exist, she couldn't possibly be head over heel for Chat because, well, he wouldn't be there either, therefore she wouldn't have known him. She always wished for a miracle to happened so she could have the confidence she needed to confess. Although Alya and the rest of her friends gave her support it wasn't enough, she'd always feared she'd lose him if he rejected her and, alike Adrien, their friendship meant a lot to her. Some of you may question why the name of this book is soulmates. Well........you'll get the answer to that question later on in the book.
