If it weren't for his insistent return home and his unrelenting attachment to Qin Youxuan, his mother wouldn't have ended up in a vegetative state.

...
A week passed.
Qin Youxuan was confined in a dark cell every day, waiting for her trial.
Qin Mo tried to bail her out, but a murder charge could not be bailable.
He visited her in jail once, but said nothing, only looked at her with a fixed gaze and then left.
Presumably, he must have already accepted the fact that she had lost her ethics, to the point of contemplating murder to compete for the inheritance of the Qin Group.
Jin Chenye did not show up even once. Instead, the people from the Meng family kept causing a disturbance at the police station, demanding an early trial for this murderer.
A murderer...
She was clearly the victim, but no one believed her.
