Do you have the link for the picture?

Their account is private on instagram so I'm not sure if it will.
It's a bit hard to find the description based on a single tweet. Maybe you can screenshot and upload it on imgur or any image hosting site? We may be able to help if we see the picture (●'◡'●)ﾉ

Trying to look for this manga (saw it from a picture). He lifted up his shirt exposing his nips and body (it was a striped long sleeve), wore a collar his neck and there was like money around him? The art looked beautiful. Any mangas similar to my description?
