Meng Chuyue's face was composed as she seriously replied, "That day... Aunt saved me, but I couldn't save her. I can only join you in seeking revenge for her."
Meng Chuyue felt somewhat guilty about Qin Weilan's death.
She didn't remember the cause of Qin Weilan's death in her past life, only that she also died that year.
She had painstakingly recalled the details of that day, realizing that even if she hadn't been there, Qin Weilan couldn't have escaped the pursuit of those people; judging by the killer's efficiency, the likelihood of them sparing Qin Weilan once they caught her... was very small.
But she did indeed affect the timing of Qin Weilan's escape...
She couldn't help but wonder if Qin Weilan might have had a chance to survive if Meng Chuyue hadn't appeared and Qin Weilan hadn't kindly saved her...
Partly due to this guilt, and also because she indeed felt a special affection for Shen Ci, she decided to join Shen Ci in seeking revenge for Qin Weilan.
