Haiku - Complicated love

I like that poem quite a lot.
(I am not that good with poems or haiku, so I'll just give you my impression and thoughts on this. Perhaps it is more analysing than giving critique. I hope you don't mind.)

The first line of your haiku refers to chemistry and respectively to spells,
both things are quite the opposite. Chemistry is scientifically based on facts, whereas spells look like something out of fantasy novels.
However, in the context of your haiku and regarding the headline both fit very well.
Chemistry may be referring to the complex biochemical processes we call love. On the one hand quite difficult to understand (the process) on the other hand easy to understand because it scientifically depicts what love is.
The same thing goes for a spell; it's difficult and easy at the same time (referring to love). The one "under a spell" easily understand why they is in love, others may not.

"They say" love is simple but actually it's not! Wether chemistry or spells are simple or not always depends on the person who gets in contact with it. Thus the second line in your haiku gives the first line its meaning or at least it is a wonderful way to let the reader think about the first line.

The last line then seems to be a conclusion: "Who cares if love (is or) isn't simple." Everyone has to decide for their own. (This is how I understand it at least.)

All in all it is an awesome poem (haiku), the different lines support each other, let the reader think about it's meaning and restart reading at the beginning just to don't miss a thing.
(When I got Wikipedia right this is what haikus are about and thus you did a very good job!)

Keep up the great work.
