Mr. Pothos who is not feeling well

good morning. Today's photo is Pothos. Unfortunately this Pothos is not feeling well. . . 😢 Several new leaves have grown, but they are turning yellow and the outlines of the leaves are dying. When I bought it, I put it on the top of the shelf expecting a pothos curtain to grow, but the vines didn't grow at all. I'm worried that it will dry up like this. . . 😢
