On a rainy day, the elite salaryman Amakusa Ryo almost falls down some stairs when he is saved by an ordinary high school girl named Arima Ichika. 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...
Oh, that's great! I can feel 
the icy needles in those words.
!جميل! الكلمات الباردة تسحرني
Oh, gefällt mir! Deine kalten Worte
sind so charmant! Mehr davon!
Oh, è fantastico! Sento proprio come se
ci fossero degli aghi di ghiaccio nelle tue parole.
Oh, muito bom! Posso sentir
os espinhos nessas palavras frias!
О, как это чудесно!
Слышу ледяные нотки в твоём голосе.
