If you were to ask Bai Wanrou what her biggest sentiment is right now, she would tell you, it's regret!
Yes, regret!
Gut-wrenching regret!
She shouldn't have left because she couldn't handle hardship, she shouldn't have listened to her mother. She really shouldn't have!
The worst mistake she made was ignoring Su Yan's advice and listening to her mother instead.
He was so strong, so omnipotent, yet she did not believe him. She should not have ruined her life for her mother's selfish desires!
She shouldn't have! She really, truly shouldn't have, she regrets, she really does regret!
Every single day of the past six years, that regret has been tormenting her; that torment is the source of all her agony.
"Rest assured, no one can hurt you anymore." Su Yan cannot promise her anything, he is a thing of the past for her, he cannot give her what she just asked for.
When she first left him, causing him to lose a bet, their relationship had already become a thing of the past.
