Since it was his mistake, he had to correct it.
Before becoming Conan, only one final confession had stood between Ran and him. If he had been a little more proactive back then, perhaps...
However, "Shinichi Kudo," that guy who had immersed himself in detectives, deductions, and all kinds of cases, probably would never have taken the initiative to speak up.
Conan smiled bitterly to himself. If he had not joined the Chat Group, if he had not watched his own Memory Copy, he probably would not have realized his past mistakes even now.
Fortunately, he now basically possessed the strength to protect himself, Ran, and the others. He had also told Ran his identity. Although after learning the truth, Ran had punched him while blushing furiously after her initial shock, the two of them had finally broken through that last barrier between them.
His only regret at present was that APTX4869 was still affecting his body. Even though he had cultivated the Haki system and raised his physical abilities to a level far beyond that of an adult, he still had not broken through its restrictions and returned to his original form.
Still, that was not much of a problem. As his strength grew and his life level rose, the rate at which the cells in his body multiplied would increase, and his body's recovery process would gradually speed up as well.
After obtaining the Death God Aura as a reward this time, he was confident that he could completely break APTX4869's restrictions within a year at most.
After all, he had yet to fully fuse with the Death God Aura, so he did not know how much of a boost absorbing souls would give him. If the increase was large enough, that time could be shortened even further.
