会社を辞める宣言をした七苗（川口春奈）は、有給消化で気ままな生活を満喫中。
不意のキス以来、コウタロウ（松下洸平）への自分の気持ちを確信し、前向きに2人の関係を考える七苗だったが、コウタロウには何か思うところがあるようで…。
一方、八海（畑芽育）は七苗とコウタロウのキスを偶然目撃してショックを受ける陽太（木戸大聖）を前に、より一層切なさを募らせていた。
さらに、ようやく邦夫（山中聡）との離婚届に判を押した六月（木南晴夏）は、最後に邦夫と話したいと思うも、その最後の一歩をなかなか踏み出せずにいて……。その様子を見守ることしかできず悩む松嶋（井之脇海）。
そんな中、失踪中の大庭家の父・五郎から一枚のハガキが届く。
Nanae (Haruna Kawaguchi), who has announced that she is quitting her job, is enjoying a carefree life with paid leave. Since the unexpected kiss, Nanae is convinced of her feelings for Koutaro (Kohei Matsushita) and thinks positively about the relationship between the two, but Koutaro seems to have something on her mind. On the other hand, Hakkai (Mei Hata) is even more sad in the face of Yota (Taisei Kido), who is shocked when he accidentally witnesses the kiss between Nanae and Koutaro. In addition, June (Haruka Kinami), who has finally signed the divorce papers from Kunio (Satoshi Yamanaka), wants to talk to Kunio for the last time, but she ...... unable to take the last step. Matsushima (Umi Inowaki) is worried because he can only watch over the situation. Meanwhile, a postcard arrives from Goro, the father of the Oba family, who is missing.
