How do i help my plant?

I have an indoor plant that a friend gave me. I don’t know what it is. It has just one stem, with two shoots off of it with heart shaped leaves. The leaves are pretty large. The larger one has now turned yellow with red around the edges and I am worried it’s going to die! Then my plant will have only one leaf! I can’t find any good plant ID sites. Thoughts? Its kind of weird because one leaf is fine…......
