I love you so deeply that I can never tell you.
We are friends and will always be friends.
Some words are destined to rot in your heart. Some injuries are destined to be difficult to heal. Some things are destined to not be erased. Some people are destined to be irreplaceable.
(This article is about a girl who fell in love with her friend who grew up together, but she did not have the courage to speak out because she was afraid that they would not even be friends in the end. So it was a tragedy.)
