Gu Xiaonuan can no longer experience her past life, because she seems to have started to get used to her current life.
Gu Xiaonuan would never change her attitude towards her relationship with Si Yuchen over trivial matters, after all, this is not the situation she wants to see.
Si Yuchen might also be very aware of what Gu Xiaonuan is thinking, but he doesn't want to say it.
If Si Yuchen were to say so to Gu Xiaonuan, then he wouldn't be like this.
Gu Xiaonuan would absolutely get angry with Si Yuchen, and she would stay angry.
Gu Xiaonuan, no matter what, could never treat Si Yuchen with the same tolerance as she did with Gu Xijue before. After all, Si Yuchen is not Gu Xijue, nor is he the person Gu Xiaonuan wants to protect.
Gu Xiaonuan has too many extravagant hopes, but she certainly won't realize them with Gu Xijue.
That's why Gu Xijue became Gu Xiaonuan's past, while Si Yuchen became her future.
