I am Beyond Birthday. Here is the story of why I hated L.
A long time ago, centuries it seems, I lived in large mansion in England with my parents and my twin. We were quite happy and L and I loved each other like the brothers we were.
I Refuse to reveal my name, nor L's so I will just replace our names with out current aliases.
L got sick. So sick he was nearly dying. And coughing up blood all over the pure white sheets of his bed. He was always so weak he seldom went outside, when he did he shivered even in the spring. Forget about school. My twin was so smart he learned from the textbooks and tutors. He was inside so much he grew pale. His coughing fits kept the ill boy up all night and when he did sleep he would wake up and not be able to breath. So he learned to hate sleeping. L had, had little social interaction with any of his peers like I had so he practically became a sociopath. So while I was playing outside at recess, sharing my jam, and having fun, he was holed up in his room whithout any social connections.
Still, I loved my brother and helped him out through the awkward introductions when he met someone new, and when we were together I knew he felt stronger.
Then some crazy psycho murdered our parents (you seem surprised, I Beyond Birthday the heartless insane murderer is calling somebody else psycho.) he was caught, and put in jail but it's not like a jailed murderer brings back our parents.
