She was only worried about Yiyi.
This girl must have some fondness for Ling Kong, otherwise she wouldn't be so impulsive. But it's hard to say whether this fondness is temporary infatuation or something else.
This girl has always been inexperienced in matters of the heart, completely unaware of what love is. Liking alone is too fragile a foundation for emotions, unable to withstand any tests.
She had been through it herself. Back then, there were countless ups and downs with Third Young Master Jun. If it weren't for the deep love they had always shared, they would never have come this far. Therefore, she clearly understands the fragility of this kind of affection.
However, you're right, it's just an engagement, not a marriage.
Perhaps she doesn't need to worry too much. There's still plenty of time for the girl and Ling Kong to build a strong relationship. In the future, when their love deepens, marriage won't be an issue.
