She always thought she was in love with the high school classmate she had had a crush on for three years, but when he confessed, she was not as happy as she imagined.
It turned out that her heart had been lost a long time ago, to the man who rescued her on the train, took care of her during military training, chased away gangsters on rainy nights, and called her "Little wild cat, jump down, I will catch you!" That person was too good and out of reach, so she made up her mind to break up with him completely. But she would receive birthday gifts from that person in those three years. She deceived herself and thought it was a rich man's support for a poor student.
Until they met again three years later, he was better and more powerful than when they first met, and he already had a girlfriend. She deceived herself that she only came into contact with him for work, but in fact she never let go. He is overbearingly possessive of her, but he is unwilling to openly fall in love with her.
In a fit of rage, she ran to India to do volunteer work. She saw a lot of suffering, and when he found her again after going through hardships, she forgave him and they finally came together.
They thought they could live happily after a simple wedding. Unexpectedly, he was shot while trying to save her during the wedding, and his life or death is unknown.
She firmly believed that he would come back, and she raised her son alone. Five years later, she finally waited for a Mr. Gray who looked like him but was not him...
Concept: All encounters are reunions after a long absence. People who love each other will recognize each other no matter how long they have passed...
