The male lead left a token behind before departing. The female lead was later found, and due to her sister impersonating her, she was wrongfully imprisoned. Years after her release, she found herself in danger once again, only to be reunited with the male lead through their child.

In the end, they jointly exposed all lies and conspiracies at an engagement ceremony, bringing the truth to light.
