Yes, he thought about helping Ariel at least once.
"I owe you one."
"Whenever you are in trouble, just call out my name, and I will be there to help you.", Rex said with a smile.
Ariel was surprised by what he said and laughed it off.
"Yes, I will surely call your name first when I need any help.", she said sarcastically.
Although she didn't believe him, she thought that it was nice of him to mention something like that.
Regardless, she seemed somewhat interested in him. It was not only because of his looks but also because of his wisdom and wise words.
His mere presence seemed different – only those of the top could recognize such aura and presence.
