A fatal attraction is common
And what we have common is pain

from Kendrick Lamar (Ft. Drake) – Poetic Justice Lyrics on Rap Genius

Meaning

A fatal attraction is a situation where a spurned partner in a romance turns vengeful, often murderous. This is wordplay though: something “fatal” can be causative of death and therefore “pain,” which is what they have in common.

Referring back to Sherene, the fatal attraction that left pain around them along with them having their painful upbringings that makes them meant for each other.
