Narcissists have an innate need to be the Centre of Attention when other people are around. They will be loud and boisterous, all in a pretty charming sort of way. They will command the attention of those around them. If they pick you as their next Target, you will be on the receiving end of their endless charm. That endless Charm is really another aspect of Love Bombing.
Why have you become their next Target? Because they want something that you have, or can give them, or your status can also shine on them when they are constantly seen by your side.
Narcissists can be pretty Charming, until you understand why they are being so Charming.
The video below discusses Narcsissistic Charm as being a Red Flag which one can look out for.
