Did Soft Serve Ice Cream Make Them Full? Chiikawa and Hachiware Falling Asleep in the Rakko's Car is Too Cute

In episode 101 of the anime "Chiikawa," Chiikawa (voiced by Haruka Aoki) and Hachiware (voiced by Makoto Tanaka) encounter Rakko (voiced by Yuma Uchida) in a car and are taken on a drive by him.
In episode 101, after showing Chiikawa and Hachiware eating soft serve ice cream at a service area, Rakko gives them a ride in his car, saying he has something to show them. They arrive at a place with a statue standing on a pedestal labeled "Kinenkouen-kun." While looking at the statue, Rakko nostalgically recounts, "One day... I made a vow to this statue... to become stronger..." It seems Rakko intended to share these words with Chiikawa and Hachiware, but as they had fallen asleep in the car, they didn't hear him.
