You like friends clearly, so you find friends interacting interesting. Someone else might like a certain genre of music or two different muscians, so if two people involved in that field work together they'll make something interesting and new for people that like that stuff. Their level of intimacy with each other is just something on the side that can make the content more interesting depending on if you're invested in that, it doesn't bring any particular meaning besides them liking each other.
