If what Tian Xixi said is true, then Lan You'an hasn't excessively offended anyone.
It's unclear whether the police have investigated Lan You'an.
If they have, it's consistent with what Tian Xixi mentioned.
Then, this case is very detrimental to Gu Jiajia.
Tian Xixi said Lan You'an had no secrets with her two daughters.
Her two daughters have no secrets with her.
She hasn't heard from her daughters whether Lan You'an was romantically involved.
Tang Huai speculated that Lan You'an had neither a love rival nor an enemy.
The perpetrator might have framed Gu Jiajia by killing Lan You'an.
This plot must have been set in motion by the perpetrator a long time ago.
Moreover, the perpetrator has been watching Gu Jiajia, knowing her every move.
Lan You'an and Gu Jiajia left the hospital one after the other, arriving at Guanyin Mountain at almost the same time.
Yet, the perpetrator was able to gain Lan You'an's trust, luring her to Yuhua Hall to be murdered.
