She returned from undercover work.
He waited five years for her.
He was her salvation; she was his faith and his light.
After five whole years without a word, she appeared at a gathering.
Her presence still made his heart race.
When she saw him again, her heart raced, but she couldn't get close. For a while, she felt trapped in a mire. His life should be filled with sunshine, she thought, not burdened by her past.
They pushed and pulled at each other until the day they finally opened up.
Then he understood the responsibility and mission she had taken on,
and the one belief he had held onto all along.
He realized that no matter how unworthy you feel, in the eyes of the person who loves you, you are always the best.
His heroine had come home. They would be together forever.
Five years later, she was still rebellious, with a melancholic air about her. Once, she had been trapped in darkness and despair, covered in scars, and believed she was no longer worthy of this untouchable heartthrob.
Five years later, he had become the man he once aspired to be: an outstanding chemistry professor and the untouchable heartthrob on campus, admired by everyone.
The heroine performs a mission and returns to the hero. I highly recommend watching it.
