Remove Two People Seamlessly

I have a single photo featuring four people. I only want Person 1 and Person 3 to remain visible; the other two need to disappear without a trace. The final image should feel completely natural—no obvious cloning marks, blurred edges, or lighting inconsistencies.

Please keep the original setting intact. I do not need any extra background work or replacements; simply remove the unwanted individuals and retouch whatever remains so the scene looks untouched.

When the edit is complete, send me a high-resolution PNG file.
