best result i could find was this: https://www.duitang.com/blog/?id=16365340
no idea who drew it tho, seeing as duitang seems to be a website similar to weheartit & pinterest :/
Found the extracted PNG version, then found a version with a background that looked rather unedited, and here it is ¯\_(ツ)_/¯
Though looking at it now, even the edited wallpaper version is on shuu.
