Tsubasa is ordered to score high on exams, so when the lovely Rena offers to tutor him, he accepts. He soon realizes that Rena expects a reward for her help. Minami spots them together and is thrilled at first, but then starts to feel very uncomfortable.
You should take care and go to 
bed, too, Shiki-kun. Good night.
عليك الاعتناء بنفسك والخلود للنوم أيضاً
يا شيكي-كن، طابت ليلتك
Überanstreng dich nicht und geh nicht
zu spät ins Bett, Shiki. Gute Nacht.
Cuídate y acuéstate tú también.
Buenas noches.
Cuídate y acuéstate tú también.
Buenas noches.
Va te coucher tôt, toi aussi.
Cerca di dormire anche tu, Shiki-kun.
Não exagere e descanse bem
também, Shiki-kun. Boa noite.
Не засиживайся допоздна, Сики.
Сладких снов.
