Well, this went better than expected.
I once tried introducing two of my female friends to each other, and they seemed to get along on the surface, but after the meeting, they both told they didn't like the other party...
I don't get the direction either, but it doesn't look like it'll be a harem; reverse-harem maybe. More than anything, it looks like it'll turn yuri if the second girl has anything to do with it.
