Talent isn't enough

Lyner looked at Niel dumbfounded at his request. Is this kid nuts? Why would he want him to be his teacher?

'Well I am technically a teacher in this school, and I'm also his adviser in the club, but why should I even teach him anything?' 

Also, what should he teach him, Lyner was simply a teacher in name only. He wasn't really a certified teacher.

"Kid you're asking the wrong person. What do you want me to teach you, anyway?" Lyner scratched his head sounding a little irritated. 

"I want you to teach me how to be a merc." When Lyner heard Niel he thought he heard wrong, Lyner cleaned his ears with his finger and he asked Niel just to be sure.

"Did you just say that you want me to teach you how to be a merc?" Niel nodded his head resolutely. Seeing this action made Lyner sigh.

"Hey kid, I don't know what kind of misconception you have on being a merc but being one is more difficult than walking through hell... Well, not like I can talk."
