If, at the beginning, Tan Jincheng certainly treated Yun Chu as Gu Yi'an's substitute.
Then later, he was able to distinguish that she was different from Gu Yi'an.
At that time, he did not expose or face it because he wanted to deceive himself!
Now, even if he wants to avoid facing it, he can't anymore.
Yun Chu is Yun Chu, not Gu Yi'an.
Aside from sharing the same body, there are no other similarities between them; they are completely different people!
So...
So essentially, falling in love with Yun Chu meant he'd already betrayed Gu Yi'an.
He once deceived himself by saying he fell in love with the amnesiac Gu Yi'an.
But when a person is just amnesiac, many habits and personality traits will not change significantly.
Yet Yun Chu, she was not the amnesiac Gu Yi'an; she was a complete personality with no relation to Gu Yi'an's soul.
He fell in love not with the amnesiac Gu Yi'an but with Yun Chu, a brand-new soul!
Therefore.
