Their meetings with Sakamoto were great!
Kubota was the best one by a lot, it looked like he was proposing.
The ones about the eraser and the books were ok too, the umbrella one wasn't that great.
I haven't noticed that Kubota and his mother were so much alike, that was sweet.
I love how Winter Sonata's music start playing in the background. It cracks me up especially since I loved Winter Sonata and watched it very seriously. It's just too funny to watch how Kubota's mom becomes so serious.
