I no longer want to be a part of this triangle

It took a single slap for me to wake up to the reality behind her feelings. My crush of two years slapped me for something I didn't do, and my best friend, the one whom I trusted the most, used the opportunity to console her whilst looking at me with disappointment. It was when darkness began to surround me, threatening me... that you appeared. The one I used to think was a boy turned out to be a girl, disguised so she could watch me. I couldn't understand the difference between love and affection, but you helped me realize the true meaning behind each and every one of them... And in exchange, I would devote myself to you...to us, for the rest of my life.
