Fading footsteps. Overlapping memories. It all started with the promise made that day. One who couldn't be honest with herself. One who constantly looked away from the truth. Will Yuu and Suzuka be able to face their true feelings?
I'll be counting on you in 
high school, too, Onii-chan!
Ich zähle auch in der Oberschule
auf dich, Onii-chan!
¡Cuento con tu apoyo en preparatoria
también, hermano!
¡Cuento con tu apoyo en bachillerato
también, hermano!
Même lycéenne,
je compte sur toi, Yû.
Spero che mi starai vicino anche
alle superiori, onii-chan!
Conto com você no colégio
também, Onii-chan!
Брат, надеюсь в старшей школе
 у нас будет всё так же хорошо!
