"Anyway, I'll see you later, love. I promise."

Kenneth had always been your best friend. Your non-biological little brother. Your comfort, your happiness, your lifeline incarnate. You have loved him for three years now. And because of the relationship he already had with you, he had no idea. Oblivious as always, your innocent little friend.
So it's no surprise when he starts dating the closest you have to a female best friend. She's ruthless, mean, selfish, and will do anything to get what she wants. Including trample all over the guy she's fully aware you're head over heels for to get closer to a modelling agency.
As Kenneth falls in love with Mia, she watches you break in silence.
Of course, Kenneth notices you seem off and offers multiple times to break up with her so you're happy, but you refuse twice as many times to make sure he is.
