Well, because there is no review for this one, I write short one. I give it a solid 6. It was interesting enough for me to read through, but nothing special. It has mild Yuri content, so if it bother you, than avoid it. You don't loose that much, if you miss this one. What is this all about? If you read the synopsis you may expect to read some criticism of religion, but there is nothing much about it. It mostly about bullying, mental illnesses, and mild sadism. You kinda get to see into the minds of the bullies. So this isn't the most comfortableread. Most of the characters are quite repulsive. Although, that is exactly what the manga wanted you to feel. Ayeon is the only one who is not enterly unbearable, but her character is kinda meh.

Visually it was in uncanny valley. So, I don't like the artstyle, but that is kinda subjective. It wasn't ugly, it was just weird to me.

All in all it is far from a masterpiece, but it is a interesting enough to kill some time.
