"Innocent Hearts Collide: The Full Volume of Teen Love, Societal Intrusion, and Private Vulnerabilities (Vol. 1)"

Another angle: if "ass" is part of the phrase "assessing", but that doesn't fit here. Alternatively, maybe "as" in "as they love it". Not quite. Maybe the user is using "ass" as part of a play on words, but that's unclear. private+innocent+teens+love+it+up+the+ass+vol+full
