Help me plz! I can't find it

I'm trying to find a book called

"Hourglass" it was a minsung book

(Little description) based off memory

It was where Minho had an abusive boyfriend who only used him for  his body. And of how obident he was. Minho bf's name was Jaeyul  (like that but spelled a little different I think) and Jisung worked at a cafe that Minho would go to everyday at 3:30pm or 4:30pm and get the same thing. And at the cafe you have an hourglass at each table to a specific time and when this time is up. You leave. Minho came to this cafe Jisung worked at. And Ji noticed something was wrong when Minho came in one day with a black eye.

that's all I remember .

Here is what the cover looked like

I believe it was written by someone with the user of: @LOV3ST4Y_MINSUN9.
Or @Lov3st4y_minsun9

If the author is reading this

Please bring it back. It was such a good book.

Or maybe you took it down for re-writing
Or you changed your user.

let me know if you are reading this !
