Onii-san

Onii san 

1.Japanese for "Big brother"

2. The incest trope that makes up 80% of anime (anime and irl japan are often in stark contrast with each other)

I always felt special being his little sister, especially when he brought home presents just for me and no one else. I wanted to be with him wherever he went. I was so in love with my onii san
