Jian's eyes widened in disbelief, whereas Drai dropped his head and pursed his lips, feeling quite dismayed.
'So it's just like what I'm afraid of,' Drai silently said to himself. After witnessing his rapid progress be met with Jian's frustration every time, Drai couldn't help but think that his other friends could have also secretly harbored similar feelings, which wasn't a good thing.
And what made Drai feel worse was that he didn't deliberately rush his progress either. Of course there were the fights during their venture and the professor's research, but he was mostly just striving to get stronger while enjoying the process. And he didn't have any particular reasons either for his hard work rather than building muscles and preparing himself if he ever ended up in a situation where he could avenge the titans.
