In order to let Bo Siyan survive, leaving him was her choice, so afterwards when he suffered amnesia following his surgery, she did not blame him for his cruel attitude or the harsh words he spoke.
Later, in trying to rouse his memories and to rekindle his feelings for her, she made every effort, strived, and did everything possible; however, the results were unsuccessful.
She was once so certain of Bo Siyan's love for her, confident it would never change no matter the time, place, or circumstance. She was so confident, so proud, but reality harshly slapped her in the face.
What she thought was eternal was actually nothing like that.
Of course, she didn't blame anyone, but she couldn't help feeling somewhat disheartened.
Now, Bo Siyan had come back to find her after regaining his memory, but what if he hadn't recovered his memory?
Even if it seems self-indulgent, there's always a slight discomfort in her heart.
