Does anyone know how the Korean drama Stairs to Heaven ends?

Taihua sacrificed his cornea to Shu Jing, and Shu Jing and Cheng Jun spent their last good time unconsciously. After her death, Cheng Jun played the piano at the seaside to remember her. She wanted to go with her, but she hasn't, so please wait for him in Shu Jing. They will meet in heaven.

The ending was beautiful. I didn't feel particularly sad. Maybe it was because the previous plot was too sad, and the ending made people feel natural and warm. Kwone Sang Woo's performance was really great!
