Because your work is so professional I will give you my professional opinion on the matter.
The animation is top notch and I would hate to see it changed while there is no actual dialog that I can understand each action speaks for itself allowing you to understand whats going on in the story along with each persons intentions. It seems obvious that the Juga and Shumadan both like Yusi and compete for her affection while at times using it to get what she wants or to amuses herself.
It seems to me that they are in Juga's jungle a less advanced place that is also innately magical while Yusi is visiting from a highly advanced place with lots of technology that seems to be spoil the inhabitance as seen with Yusi's actions in this animation and others where both Juga and Shumadan both try to keep her happy and entertained. Shumadan is a little more complicated he seems to be from a very authoritative place something similar to Russia though not much has been reviled due to his passive nature I know that he is honorable and will risk it all for his friends even Juga the more overly mischievous one who wants nothing more than to gain Yusi's favor.
