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...
You hadn't contacted me in a while, 
so I was wondering what was going on.
.لم تتّصل بي لفترة، فكنتُ أتساءل ما الّذي يجري
Da du dich schon eine Weile nicht gemeldet hast,
hab ich mich schon gefragt, ob was passiert ist.
Hace mucho que no me llamas,
así que me preguntaba qué pasaba.

Tu m’as pas donné de nouvelles,
je m’inquiétais pour toi !
Non mi hai più contattato. 
Mi chiedevo dove fossi finito.
Estava me perguntando o que aconteceu
com você, pois não fala mais comigo.
Ты давно не писал и не звонил, так что
мне хотелось бы знать, что и как.
