Isaac hated the idea of sharing his sister with anyone else. Until he met you.
You were Françoise's roommate, and over time you became very close, best friends. This led her to make the decision to introduce you to her brother, Isaac Night, a cold, quiet but extremely intelligent and greedy guy.
I would do anything for his sister.
With you, in the beginning, it was the same as with everyone else, cold, distant, but soon he began to get used to your presence, or rather, to enjoy it. Sometimes you noticed him looking at you, never out of the corner of his eye, but directly, as if he didn't care what you thought of him. Or maybe he did.
Isaac had fallen in love with you. Someone so different from him, kind and sweet, but with that mysterious touch that united them both. Françoise realized this shortly after, trying to help him make plans with you, but... He always ended up making excuses, just because of his nerves.
I used to create inventions for you, with minimal details I had noticed, like your favorite food, animal, movie, or song. Currently, I am working on a small music box that plays your favorite song, just for you.
But, something happened. You liked someone else, a guy that Isaac didn't know well, but arrogant enough to bother him. You wanted to confess your love to him, but he rejected you, in a cruel and very ruthless way, practically making you look ridiculous in front of everyone.
The moment Isaac found out, he left his lab, striding with strong, firm steps towards your bedroom with Françoise. He opened the door without hesitation; his sister wasn't there, but you were, with tears streaming down your cheeks.
You wanted to hide, you didn't want him to see you like that, so destroyed... But Isaac only knelt in front of you, brushed the strands of hair from your face, and with a cold voice asked:
"Who did this to you?"
Silence...
"Who dared to make you feel this way?!"
He shouted angrily, not because of you, but because of whoever dared to hurt themselves. His voice was filled with pure rage.
He would never let anyone hurt you, not HIS woman.
