Well this is great.
my crush in school is a year older than me but that has nothing to do with the real problem, you see only two people in my school have the same last name as my crush.
Those two people are my crush and his sister.
His sister is in the same year as my older brother and she is starting serious beef with my brother and his girlfriend.
So, my brother hates my crush and when I told my friends they went up to my crush, and told him to tell his sister to back away from my brother.
