I feel bad for everyone, but I feel bad for Ob oom the most :((( I understand her actions. I don't think she was being manipulative there, rather, she's mentally unstable and has just recovered. It must be so hard for her. I also understand why Ai chose her, something worse might have happened if she had chosen May instead. I think once Oom is more stable, sheβll think things through better. (The part where May was crying broke me π)
