Any manga like this?

Office setting or something of the sort, kind of hierarchy based.
The ML is the 'boss' so to speak or someone who is very powerful and he is very cold & hard on his subordinates but is secretly 10x harder on himself and overworks and stuff & maybe tragic backstory.
If ML is a bottom I'd like that, but top is okay too. I just want some fluff and comfort and healing and angst.
It would be preferable if MC (Female or Male) is ML's subordinate.
