After hanging up the phone, Nanahara Takeshi pondered for a moment before smiling at Kiyomi Liuli, "Alright, it's time for us to take our leave." Sugita Mai didn't really need them there, and now that the method of the crime was clear, there was no point in staying any longer.
Kiyomi Liuli felt a bit regretful. It was rare for her to find a peer who could discuss mystery novels with her and she wanted to chat more, but there was nothing she could do when Nanahara Takeshi was ready to leave. She reluctantly said goodbye to Sugita Mai.
Sugita Mai saw them out, Kiyomi Liuli lingered reluctantly and promised to send over some classic mystery novels and comics later to help her pass the time. It seemed she was planning to turn her into a fellow enthusiast.
Well, she quite liked this young lady, Sugita Mai.
