It's not that Gu Beihan stopped liking Qin Xue after leaving, but because he knew she only loved Chu Molin, he didn't want to disrupt her life, so he left due to work.
Who would have thought that after almost a year, the person he hadn't seen would appear before him.
Initially, he saw that those people weren't good, afraid she'd suffer, so he thought of bringing her back, not realizing that the more he looked at her, the more he stirred up feelings buried in his heart.
Thus, these emotions governed his thoughts, leading him to do such things.
But he didn't intend to completely seal away her memories.
Because that was something he didn't want to see; as long as Qin Xue felt she was doing well, it was enough.
Moreover, to some extent, she loved Chu Molin. He also wanted to see if, after he did such things, she would continue to think about Chu Molin and love him as always.
It could be said that Gu Beihan had several intentions behind doing this.
