One might say Shen Biran is excessively harsh on Gu Qingyuan, but there is a reason for that.
After all that Gu Qingyuan has done, isn't Shen Biran allowed to have any discontent towards him?
After Gu Qingyuan did all this, he should have anticipated the kind of outcome he would face.
Moreover, it is only at this time that Gu Qingyuan and Shen Biran realize why he had to do this.
All his actions were to earn Shen Biran's forgiveness, but Shen Biran finds it difficult to forgive Gu Qingyuan so easily.
Gu Qingyuan has already lost the eligibility to be forgiven by Shen Biran, and Shen Biran has made her utmost effort, but no matter how hard she tries, isn't the result the same?
No one is curious why Gu Qingyuan is as he is now, but it must be said that even if things were not as they are now, a reasonable argument is needed to convince Shen Biran.
Obviously, the other party doesn't have such ability, hence there is no need to consider how to persuade the other party.
