I was about to tell him to fuck off, but I couldn't do it in front of Lys, so I had no choice but to swallow my comment and continue with what I was going to say
"Actually, I'm very good at runes and can teach, as I was even appointed assistant to the A-class rune instructor."
"Oh, is that right? I thought you were a swordsman since you knew so much about swords, but now I see that you are a competent mage."
"No, I'm not a wizard, I'm a..."
"Listen to this, Lys (≧▽≦*)/. Believe it or not, Chris is an unarmed warrior, but he knows so much about runes that he was chosen wizard. Isn't that amazing? Besides the instructors, there's no one who knows runes better than him."
'Damn it, William, stop interrupting me. I'm trying to make a good impression here.'
Well, since he praised me, I'll forgive him, but I'll make sure it's the last time.
