"Great, you two are eighteen now. Let's celebrate today and tomorrow I will take you for Law Formalization."
Du You's words brought both joy and worry to the sisters. What if they fail to complete Law Formalization? If their star grade is low, the consequences might be problematic.
But if their star grade is high, their future live might be secure.
Speaking of which, after spending time together, they now understand Du You much better and don't fear or resist him as much as before. However, the thought that they might not fulfill their master's expectations still made them very nervous.
Thus, their birthday was spent in a state of anxiety and unease. This was the first time the twins celebrated their birthday without any other family members, only with Du You, their master in name.
