Sometimes love is so strong, it makes a person do things outside of the realm of their norm. And when love is overriding a person's every emotion, and the one that they love is in trouble, a person will go to great lengths to help.
Even if it impacts every aspect of their life. Even willfully putting themselves in danger.
When love overrules all of your thoughts, and envelopes your heart profoundly, it is impossible to not want to protect the subject of your affection.
No matter the cost.
