At a time when Goro (Matsushige Yutaka) is busy, his lower back hurts once again. The doctor (Kitamura Yukiya) suggests he be hospitalized so he could make thorough examinationof his health. Goro hesitantly obliges. Three days later, Goro is in his hospital bed being served dinner by a nurse (Sudou Atsuko). Goro is looking forward to the hospital meals, which he deemed "has improved considerably lately". However, his meal this time was disappointing, and describes the flavor as "thin". Then, the doctor comes to check on his progress. He says Goro is ready to be discharged the next day. However, for no particular reason, he nonchalantly asks Goro about gyoza. As a result, Goro who is yearning to eat something salty and savory, cannot stop thinking about gyoza, and had trouble sleeping. The next day, he gets discharged and decides to reward himself with a hearty meal. He chooses a ramen shop called "Saien", which of course serves his much longed-for gyoza. His wish is granted, and along with it, he orders the shop's famous dish, Jun Liver Bowl...
師走の忙しい時に五郎は腰を痛めてしまい、何と３日も入院している。仕事が頭から離れずベッドで手帳を広げていると、夕食を運んできた看護師（須藤温子）に止められた。三度の食事だけが楽しみな五郎だが、病院食はやっぱり味が薄くパンチがない。心で文句を言いながらも完食すると、様子を見に来た医師(北村有起哉)が突然「井之頭さんは餃子お好きですか？」と、美味しい餃子の食べ方（酢、胡椒とラー油）をとうとうと話し出す。深夜、餃子が頭から離れず眠れない五郎が廊下を歩いていると、入院している若い男(碓井将大)が携帯で「塩辛」の差し入れを頼んでいた。「塩辛」を連呼するその男の声を聴いていてさらに悶々とするのだった。 寝不足のまま翌日退院した五郎。快復のお礼もかねて亀戸天満宮にお詣りしようとした途端、突然腹が減った。「やんちゃなメシをがつがつ食いたい気分…」そんな時ラーメンの暖簾が見え、思わず入り、カウンターに座る。
まずは餃子を頼む。その後店の壁に貼られたメニューを確認していて「純レバ丼」という文字を見つけた五郎。なんだこれは？と頭をひねっていると、若いカップルが入ってきて2人して純レバ丼を頼んだ。五郎もすかさず乗っかって注文してみる。やがて昨夜夢にまで見た餃子がやって来た。酢と胡椒、ラー油で食べて満足。間もなく刻んだ長ネギの山の皿がやって来たと思ったら、なんとそれが純レバ丼だった。カップルが自撮り棒でネギの山の純レバ丼と写真を撮っているのを横目で睨みつつも、やんちゃな純レバ丼を堪能する五郎だった。
