Thomas thinks he was always in love with Isabelle.
Ever since they met when they were children, she was always so nice to him. Over the years, she was so kind to him and always thought of fun stuff to do. If it wasn't for Isabelle, Thomas wouldn't even have a childhood and would have probably killed himself.
Thomas realized he was in love when he was older. He always felt a fuzzy feeling in his chest and that's how he knew.
He felt it whenever she smiled at him.
He felt it whenever they laughed together.
He felt it whenever they played together.
He felt it whenever they kissed.
He felt it when she held him during his bad days.

Looking at Isabelle smiling at him, he knows.
Isabelle is that special girl and he's in love with her.
