Help finding anime?

[ToriMorningstar]

This was a few years ago. Several in fact. I'm looking for an anime about a white haired doctor who collected dolls. He wore a white trench coat and had glasses. He also had this massive crush on a brown haired man and I believe when he died he was surrounded by roses. Any idea what this is?

Robot Carnival?

I haven't actually seen this so I might be mistaken

Bit late to this, but it sounds like this could be Yami no Matsuei (Decendants of Darkness)
