High school student Yuta Asamura begins living with his stepsister Saki Ayase and her mother due to his father's remarriage. Both Yuta and Saki, who hold cautious values regarding relationships between men and women, agree to live with an appropriate sense of distance between them.
But your birthday is a week before hers.
لكن يوم ميلادك قبل يوم ميلادها بأسبوع
Sie hat knapp eine Woche
nach dir Geburtstag.
Pero tú cumples años una semana antes.
Pero tú cumples años una semana antes.
mais ton anniversaire
est une semaine avant le sien.
Ma il tuo compleanno 
è una settimana prima del suo.
Mas você faz aniversário
uma semana antes que ela!
Но у тебя день рождения 
на неделю раньше.
แต่ลูกเกิดก่อนเธออาทิตย์นึง.
