Regarding whether or not it is appropriate to address themes such as love and attraction in your sets, i think that its ok.
The only dangerous point here is that the concepts of love and attraction are not the same Biblically and from a world view. There are emotions and feelings that are “natural” to the “natural man” (and some un-natural ones that have become accepted) – but we are not natural men… we are supernatural. (1st Cor. 15:33-48)
I’m not disagreeing with you, just wanted to point that out.
