In 2012, I fell in love with him the first time I met him.
In 2018, she wanted him to attend her undergraduate graduation ceremony, but he didn't come. She caught his sweetheart kissing him and chose to leave.
In 2021, he became a famous doctor, but he still couldn't let her go and went to find her. He still missed her graduate graduation ceremony.
She was not the girl he longed for, so he missed her again and again.
In the crossroads of time, in a three-person movie, who loses and wins in the end, she hit a brick wall and was heartbroken.
