What does this mean???
as ga41 said the tragedy is unrequited love but if you think "DEEPER" one who is unable to love or return love is worse off by far than one who loved and lost than never loved or something along those line? Imagine being icy cold for n eternity verses finding love or a lover after a brief search
The literal boy was speaking literally and actually loved the girl. The figurative girl was speaking figuratively and did not actually love the boy. The tragedy is unrequited love.
