I agree with the other reviewers about the Mum. She's a bit much in this episode. I never liked this scene in the other versions either, so I was half hoping they'd just skip it completely. But Kotoko at the end, and Kin-chan, were both great, and Naoki's little bro is so supportive and loves his brother so much, it's very cute to see. Naoki is being an idiot.
