Akira wanted to discuss the findings from the 'zombie drug' experiment with Kaito immediately after leaving the medical institute. However, she did not want to disrupt his day. In the past few weeks, he had been going to the Takahashi Corporation for work.
She was not clear about his intentions, but she thought he was investigating something relating to the Takahashi family, possibly his parents. She did not like poking his wounds, so she did not dig too much into his activities. But, she gathered from their conversations that he suspected his uncle of killing them.
In any case, the matter concerning the drug was not too urgent. She did not have to tell him immediately. They could discuss it in the evening. Moreover, she had an appointment with her aunt, Nanase, so she could not go home directly.
