The day before spring break, Itsuki has a fight with his father and asks Amane to let him stay over. When Chitose finds out that her boyfriend will get to enjoy Mahiru's cooking, she demands to join them and stay at Mahiru's apartment. The four friends spend the next few lively days together. After Itsuki and Chitose leave, Amane returns home one day to find Mahiru confronted by her mother, Sayo. Noticing Mahiru's dark expression and sensing that something is wrong, Amane invites Mahiru in. The two sit together on Amane's sofa as Mahiru timidly explains her complicated history with her parents.
I keep trying, even though I know 
it'll never change. I must be stupid.
لا أنفك أحاول، رغم علمي بأنّ ذلك
لن يتغيّر أبداً. يا لي من حمقاء
Und obwohl ich weiß, dass es nichts bringt,
strenge ich mich weiter an …
Y sigo intentándolo, aunque sé que
eso no va a cambiar. Qué tonta soy.
Y sigo intentándolo, aunque sé que
eso no va a cambiar. Qué tonta soy.
Je donne tout ce que j’ai,
même si je n’ai rien en retour.
Ho continuato a provare e riprovare, pur sapendo 
quanto fosse inutile. Che stupida che sono.
Eu ainda me esforço mesmo sabendo que
nada vai mudar. Sou uma tola, mesmo.
А я продолжаю стараться,
хоть смысла стараться и нет...
