If you fall in love with someone who sees you as a brother, I don't know whether to call it a mistake.
If you fall in love with the person your brother loves, I don't know whether to call it a mistake.
If you fall in love with someone who would never love you, even if they died, I don't know whether to call it a mistake.
If all of this is wrong, then I don't know what love is, or whom I should love.
How hard it is to love someone in this life.
