Training

Hearing that her ability could be improved, Aerine was obviously happy, and she became eager to train even more. 

"First," Mai continued, "we need to go to a compatible and comfortable place for you to practice. For example... the sea." 

This was the most suitable place for Aerine to practice her abilities. What was more, she was a siren, and so the sea was really her safe haven. 

"Let's go to the nearest coast first." Mai was already planning their trip in her mind when Aerine suddenly interrupted her thoughts and suggested something else. 

"Uhm..." Aerine scratched her nose, somehow embarrassed to bring this up, but this was the easier solution to their current problem. "We can just go to my space... well, room in the mansion." 

At first, Mai didn't quite get it yet, but she soon understood what Aerine was talking about.
