C409 Evidence
Lee Qiangkun's idea of asking Lin Qingwan out was suggested by Gu Na. The purpose was to get Lee Qiangkun to go on Lin Qingwan's bed. He never would have thought that Lin Qingwan would leave Lee Qiangkun's room unscathed and Lee Qiangkun would jump off the building.
Gu Na had seen all of this because she had set up surveillance equipment in Lee Qiangkun's room
