Gotta agree with the priest, they all have feces for brains.
If there are 3 people in the crime scene and 1 of them is dead, then 1 person accuses the other of murdering the victim but the accused denies it, then the only scenario that should follow is having both of them as suspects. A proper investigation then should follow to prove either of their testimonies. So, how come they are so convinced by Beatrice's words without a single one doubting her?
I liked this webtoon because the FL is intelligent.
But this situation is so dumb, imo.
