"After a week, we are going to Rasatala."
When Mei Wei heard these words, the smile on his face froze. If Aman was going to Rasatala, his magical realm, then it meant he was going to leave him.
Mei Wei was deeply saddened by this. But he could not stop Aman from going. He knew Aman's revenge was most important for him, and he couldn't be a burden in Aman's way.
Aman had to go to Rasatala to find Mei Wang and Sage. Because of him, Aman had already delayed his time to take care of him. He could not afford more delay.
Mei Wei internally wished that he could also go with Aman. Mei Wei knew he couldn't go with Aman. Luo Li had told him that a normal human being was prohibited to enter Rasatala. Even her father had never seen that world, even after being married to an Ichadhari Naga.
That's why he became instantly sad after knowing that Aman had to return.
But he tried to comfort himself. This day would have arrived sooner or later.
