Kean is on a straight loan at PSG to June.
After reaching the Champions League semis, Kean said: "Last year at Everton I did not play much. I worked hard during the summer and it gave me an important lesson, not to give up and work when needed.
"Now I have a coach who gives me confidence and I can contribute to the team."
But the 21-year-old does not know what will happen when his loan deal with PSG expires in June.
"I do not know. I am enjoying this beautiful moment, now we are in the semifinals. Eventually I have to figure out my future, but right now I'm concentrating on what's going on here. I do not yet know where my future will be."
