In the commercial settings, KudoKan and Matsuzaka Tori are brothers with a wide age gap.
(pardon me as my listening isn’t that good)
Matsuzaka: Older brother, have you contacted our mother recently?
KudoKan: Yup.
Matsuzaka: Really?
KudoKan: Take this.
Matsuzaka: Eh, what is this? -laughs at the picture of their mother with a photo filter-
KudoKan: This function is popular recently.
Matsuzaka: Eh~
Matsuzaka: Mother, I wonder if she is lonely.
KudoKan: I wonder too.
KudoKan: Let’s head back together this time.
Matsuzaka: Yup.
Mother: Yes?
KudoKan & Matsuzaka: We are home.
Will update if I find more details. [edit2] There is actually a [storyboard] of sorts for the commercial. I was surprisingly quite accurate -peace sign- [/edit2]
[edit] 2.5 minute worth of making and talk!
