@Thifa He might have quitted school since in Japan, highschool is not mandatory. A lot of teenagers go directly into the workforce after middle-school. It is common for them to take an apprenticeship like Kenta currently doing.
I have feeling Kenta work in Kichi Kichi Omurice restaurant. I recall they have their shop in Kyoto. They have long history (just like Mother Ichi said) and their omuric said to be best in Japan
Their silent cheering for him, his gesture he used to show off the charm they got for him... I love that he takes this exactly as seriously as everything he's done before.
