Zero only gives a slight nod to Mia.
"Please be careful in the future!"
Mia said in a tone filled with worry.
*SIGH!
She only understood now why there had been no sign of Zero for the past two years. No wonder that despite her best effort to find him, she has yet to stumble upon a single clue about his whereabouts.
( That also explains his insane growth! )
Mia thought. Greater the risk, the greater the reward. By putting yourself in constant danger, you can grow stronger but it is also very risky. That's why Mia had to reprimand Zero.
( I will have to keep my eyes on him all the time! )
Mia thought.
She was sure that Zero will again go into some dangerous situation. The incident here with the church was a prime example of that.
So, to keep Zero safe, she believed that she had to look after him all the time. Otherwise, she fears that he would once again disappear and get himself involved in something dangerous.
