Even though the point of these things seems to be to let girls hook up with guys, they always seem to send the guys in in prepackaged pairs. In Utapri, the boys were roommates and had existing relationships. In Kamigami, they're fellow gods of similar mythological houses. I just think it's pretty hilarious that they're all "Here, some guys to fantasize about, but we're going to give them to you in this slightly suggestive set." Personally, I don't care, I'm down for whatever, but it seems rather counter-intuitive to me unless you're specifically looking to hook some rabid fujoshi.
