Rough gist of the commentary: Komachi did something to earn a scolding from Eiki, so she headed straight home after work to prepare a fancier than usual dinner to regain her favor.
Meanwhile, Eiki felt guilty about scolding Komachi in front of everybody and wanted to make up with her but they never ended up meeting again during the day. She also got the wrong impression after hearing that Komachi went straight home as soon as work ended, so she was all nervous about what the mood would be like when she got back home.
