New novelist, Imachi Jun, whose debut work is a big hit, couldn't write her next work due to pressure. She decides to stay for a time at the private lodging "Kizunaya", run by Sosuke and others. "Kizunaya" is an inn that does not require payment for lodging and is limited to one group per day. The rule is "one night, one meal" and has been the management policy since the previous owner, Nanami, owned the inn. The next day, Jun, Sosuke and Kokoro go to Dotonbori. They have lunch at "Hatsuse", an okomiyaki restaurant. Jun is impressed by the excellent okonomiyaki.
