The letter said:

I am willing to feel the pain of not seeing each other thousands of miles apart with you.

I am willing to feel the suspicion and pain that the other party may be seduced by other opposite sex with you.

I am willing to feel helpless when I was not admitted to your university with you.

I would like to have your birthday every day and feel the emptiness without you.

I am willing to feel with you that every Valentine's Day can only be held in a daze in the corner with a mobile phone.

I would like to share with you my anxiety about whether we can meet again after graduation.

I am willing to feel lonely campus life with you.

I am willing to feel the lonely love life with you.

I want to feel the secretion of youth hormones with you, but I can't vent.

When she gets used to loneliness, she doesn't need you.
