Can’t find this one piece of ambient music online, please help!

Just started watching this show yesterday and holy crap I can’t believe I waited this long to watch it.

Anyway, there’s this instrumental piece that’s repeated a lot on the show and I’m trying to find it online but it’s not on the OST or any fan made list! Please help me find it.

It plays in a lot of episodes, but I can point you to an exact point where it does play: season 1 episode 8, started at exactly 45:34. Please please please help me find it!
