Even this incident, she clearly told him that they would have no more relation in the future, yet he still used the child to bind her to him without a care.
This is his character; he never lets go of what belongs to him easily.
But now, he has disappeared. The man who always chased her, clinging to her, and somewhat domineeringly possessing her, has vanished like air, completely disappearing from her sight.
When he left, he didn't leave her even a hint of message!
What kind of feeling is that?
Empty, suddenly a large piece fell away?
No, it's not just that. Besides that, she felt a sense of panic in her heart, as if he would never return and erase her from his life forever.
That, is the most terrifying!
Unexpectedly, his disappearance had such a huge impact on her heart, and before, she never realized, never thought that he would truly leave her one day.
