Despite confessing his feelings for Oko, Sataro left Edo due to unavoidable circumstances with a promise to return, but now Seiji has received word that Sataro has indeed been true to his word and returned to the city. However, Sataro has yet to come and see Oko, which leads to some suspicion that he might be missing or met with some unfortunate accident. For Oko's sake, and pushing his own feelings aside, Seiji looks for Sataro, but he is completely blindsided when confronted by Oko's true feelings.
I'm sure that to Oko-san, you both are similar 
in that you can't let go of the chains of the past.
واثقة أنّه بالنّسبة لأوكو-سان، فأنتما متشابهان 
.في مسألة عدم نسيانكما لقيود الماضي
Für sie seid ihr beide vom gleichen Schlag,
weil ihr die Vergangenheit nicht ruhen lassen könnt.
Para Okou-san, ustedes se parecen
en que no dejan el pasado atrás.
Para Okou-san, os parecéis
en que no sabéis dejar atrás el pasado.
Okô vous a certainement
trouvés incapables
Sono sicuro che per la signorina Okou 
siate entrambi fissati con il vostro passato.
Provavelmente a Oko-san os vê como pessoas
parecidas, que se prendem ao passado.
В глазах госпожи Око вы маетесь ерундой.
