What does the Korean drama finale mean?

It is said that there is a foreshadowing ahead. Didn't change it back.

This painting is broken. Hint didn't come back.

Allow in Jing Jun's body or soul.

But it's still quite tangled.

PS. I watched the ending again today. I got it back. Jing Jun may have lost his memory, but he may not lose it. It doesn't seem to be on TV. Do you remember Teacher Ji? But the director is too cruel. Don't let Jing Jun show his face.
