So that specific couple doesn't look familiar to me, but it looks like something by Sakura Haiji. I don't know if this is helpful to you, but here's a link to their stuff if you wanna look through it to find it. http://www.mangago.zone/r/l_search/?name=Sakura%20Haiji
Also, it appears to be the cover of a magazine so it's possible that it's just an illustration by that author.
Thanks bro!
No problem!
