Four years ago, he was a senior and she was a junior.
He accepted the love letter she wrote to him for someone else,
From then on, I never forget it.
Four years later, he is still a senior and she is still a junior.
She accidentally bumped into his arms,
From now on, there will be no separation.
A senior student: You bumped into me yourself, so don't run away.
A certain school girl: →_→I didn't expect you to be such a senior
