After finishing their exams, summer vacation finally begins. Masamune plans his next move to get closer to Aki, and heads to Tsunade Island along with the others to spend time at Aki’s summer villa. Yoshino tells Masamune that if he’s not able to make any progress with Aki there, she would tell Aki everything that’s been going on. Once they get to the island, they meet the secretary of the Adagaki family, Yuigasaki, and Masamune tells her that he’s dating Aki. This leads to the two having to pretend that they are a couple...
I can't figure out why 
she's so obsessed with you.
.لا يمكنني معرفة سبب هوسها بك
Ich bin auf kein Ereignis gestoßen,
das sie so auf dich fixiert haben könnte.
No sé por qué está
tan obsesionada contigo.
No sé por qué está
tan obsesionada contigo.
Et je n’ai pas trouvé
pourquoi elle te colle autant.
Non riesco a capire 
da dove venga la sua ossessione per te.
Eu nem consigo descobrir por que
 ela é tão obcecada por você.
Не могу понять,
почему она помешана на тебе.
