Ryo was dizzy from not eating breakfast, which worries Ichika and she offers him her lunch then runs off. Later when Ryo gets home, Ichika is in his living room and he finds out that she is actually his sister Rio's classmate. Ryo wants to thank Ichika for saving his life and offers to kiss her...
Damn that woman, 
making me stay up all night...
...تبًّا، أبقتني تلك المرأة مستيقظًا طوال اللّيل
Mist, dieses Weib …
Was war das nur für ein Nacht-Kurs …?
Bon sang,
elle m’a maintenu éveillé toute la nuit.
Ah, accidenti a quella donna... 
Mi ha tenuto sveglio tutta notte.
Droga, aquela mulher. 
Me fez ficar acordado a noite toda.
А, ну что за женщина,
вообще не дала ночью поспать...
