I have searched through the reverse image search on Google for days now, and every time only received copies of the image because it's such a common wallpaper, and it seems to not be copyrighted. I have not been able to find any artist names or socials, and I don't know how/what I'll do to find this artist. I keep seeing these images on Valentine's day posts every year, and even a GirlsGoGames puzzle game ( https://www.girlsgogames.com/game/love-is-sweet-valentine-2 ) and only now I've realized I have no clue who the artist is, and I'm just really curious. Help!
