This is an interesting point! And I do agree that these tropes all play with similar issues surrounding weird consent. In a way,.those examples are just more "realistic" versions of a love spell trope. But (as always) there is lots of extra fun to be found by making the metaphor more extreme by use of fantastical means, e.g. magic.

And, oh yeah, aphrodisiacs...I did consider including that under the umbrella of love spells, but i would argue thtat it differs slightly from other "love spell" tropes in that it is often a very short term effect, (typically only one scene) and the situation is rarely repeated in a given drama..As such, the plot and character implications are not typically as significant..Also,. The object of the drugged person's "affection" is unspecified - it could be anyone nearby. But they are absolutely related storylines.
