Help me find this non yaoi manhua *spoilers*

Not a yaoi, but basically it's about a boy who is in a wheel chair who gets bullied but then one day this *best* boy comes into school and is somewhat obsessed with wheelchair boy to the point where he'd kill someone for him. His personality is somewhat weird but turns out towards the end it's revealed that they are twins and they were just separated and wheelchair boy's legs don't work because an intruder came in and stepped on his leg when he was a a newborn.
