could someone please remove the background or tell me which font this is?

You need to untangle the two letters like below, but if you drag this single S to the site below, you will be offered several alteranitives, but none of them are free.

You can use the Whatfontisthis site to find out the font and use select color range to create a  selection to mask the background/

You can edit the mask to improve it some however the image to too small to do a high quality job.

You mean, surely, can someone help you learn how to remove the background with Photoshop?
