When Song Yi returned to Capital City again, Mother Han was no longer staying at the hospital and therefore, he could not make an excuse to come over to visit the elderly woman while seeing the girl he liked.
Previously, before he had taken off to City Y, Song Yi had exchanged his contact number with Mother Hand and therefore was aware of her conditions.
Song Yi was relieved upon hearing that Mother Han's surgery has been successful and that she has was allowed to return home and recuperate. He knew that if anything happened to Mother Han during her surgery, Han Yue Xiu would be sad, and seeing her sad was the last thing he wanted to see.
He could still remember the way Han Yue Xiu had cried with a grievance at the side of the road after she found out about her mother's illness.
