Hi, yet again I'm looking for the name of this description of a manga lol. I really should write down somewhere the name of the manga I've read -_-
Anyways I think it's a yaoi manga? But not entirely sure. Here goes...
It's about this detective who is investigating this murder of a homeless woman in the park (who is known for being a pick pocket?), and this guy shows up, turns out he's the woman's student(?). The detective originally thinks he's involved in the death. Anyways they end up living together (I think lol). Also later it turns out that this detective knows the guy from a while back when he tried to steal the money he got from his brother's funeral (who was killed by someone.)

Haha I'm sorry I suck at giving descriptions, too many things come to the surface of my mind and they get muddled up ><

I am pretty sure you are talking about Crystal Harem.
