Imagine that love is a virus.
Literally - a virus.
Falling in love means becoming infected.
Rapidly, you take on the personality traits of the object of your desire (the person you caught it from).
There is no cure.
There is a 50/50 chance that you will lose yourself completely, as their personality takes you over. However, you can fight to preserve as much of yourself as possible.
Tell us what it feels like to have someone else take you over and how you choose to end the conflict.
