Her conclusion in ch12 confused me

1. She was adamant to make sure lysandro doesnt stray
2. Her discovery of the truth shouldve nailed her mission deeper since she had to face lysandro and her mistakes
3. But instead here it is:
A. She couldnt believe lysandro killed his sister (as if it was foregrounded that her neglect had causes his indifference and she is aware of it)
B. She is, again and unsurprisingly, more concerned about Frey over Lysandro's mental state.

Here's another thing that has been an itch i couldnt scratch, the way Yuri underestimates her influence over Lysandro (as much as she is dense overall). She was aware of how her neglect pushed lysandro off the cliff and pursue Frey. She is also aware of lysandro's now growing affections for her to the point of pushing others away from her. But she still only ever thinks of it as childishness or half ass it with "if u dont understand, just memorize this". Like, are u serious?? At the end of the day, unraveled truth or not, she also just keeps thinking about Frey. (The timeskip also flossed over the changes she made as a saint, i feel like, they couldve done that midway the passing years...but thats just me.)

Its still chapter 12 but honestly, it doesnt interest me to keep reading more coz of those above, and the fact that she missed alot of chances during their childhood because she doesnt fully look at the situation nor does she face lysandro or frey. Everything is just a plot and her mission feels so lackluster especially now that theyve grown but only Frey showed more development (and he barely had his POV lmao)
