In people speak there is no mention of Reb Chaim and the event spoke about the family of the little girl traveling to some hotel somewhere,not an alley in Yerushalyim.Additionally, the girl wanted to dump the guy after a few meetings because of the scar and then he explained himself. A few possibilities:
A)Either the story in people speak and this one are similar but not one and the same
B)They are the same story but to help assure privacy, certain facts were changed
prior to publication in people speak
C)The part of the boy seeking advice from Rav Chaim kanievsky was attributed wrongfully, or conversly in print version or other versions it was not rightfully attributed to Rav Chaim Kanievsky.
