Yes, it' a good sign!
Liver is closely related to emotions such as anger, sadness and grief (all emotions have a "chemical" counterpart). When they clear out, there is more space for joy. If you do not evacuate the residual, withheld emotions accumulated in the body-mind, as they want to free themselves, they may create more trouble just to get your attention.
Thereafter, emotions (so-called negative or positive) may visit you and depart of their own accord; they are part of the human experience!
Have a good life!
