His undying devotion HUD

Irene Hensley, the Daughter of a director fell in love with her junior at school-Ethan, who loved her dearly. Having strict parents, she had a hard time dating him.
"Ethan, let's break up," One day, Irene said despite feeling pain inside and forced Ethan to part ways.
"I understand. I hope you won't regret today's decision and remember my words." Those were the last words he said to her before leaving.
However, ten years later, she broke free from her family's confinement and decided to live for herself without getting married.
After several attempts, she got accepted for a job where she ran into the company's CEO. The face looked awfully familiar yet foreign as she felt nostalgic and her loud heartbeat.
Being suspicious, she observed every move of the CEO, who turned out to be the person she thought he was-Ethan Marc.
He later sent a marriage proposal to her home and they arranged everything without Irene's opinion.
