For Ling Ge, Luo Ning directly branded him as scum.
Although many things the original did were voluntary, Ling Ge wasn't innocent either.
After all, before he met Leng Ying, he had always assumed the original's presence and even agreed to the engagement between the two families.
He totally treated the original as a spare tire; if this isn't scummy, what is?
If Ling Ge had outright refused the original from the start, not paid her any attention, not let her hang around or act like a puppy, not accepted her feelings,
with the original's initial pride, she likely wouldn't have continued to cling on.
If he had rejected her right from the start and she still obsessively meddled and sabotaged his relationship with his "true love", then Luo Ning wouldn't think Ling Ge was in the wrong.
The world doesn't work like "I love you, so you must respond".
But Ling Ge gave the original hope, only to personally destroy all her hopes.
