[David's P.O.V.]
Although I was very strict with training Kirk, he had never complained about it. He had always silently endured it. In the end, Kirk turned out more perfect than I had imagined him to be. However, time was too short. There was less than half a year before Kirk's coming-of-age ceremony. His current strength was far from enough. I had to be even harsher than before.
Recently, Kirk had been busy investigating his father's death, so I reduced his daily training by quite a bit to let him focus on the investigation. It had been almost two years since his father's death so if we were to start searching at this time, most of the evidence would have already disappeared. Investigating his father's death was like finding a needle in a haystack. But I didn't expect him to discover the cause of his father's death in such a short time. I couldn't help but have a new level of respect for him. He had matured so much more since the last time I saw him.
