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?
When even your real little sister likes you, 
that's proves you find little sisters moe.
Wenn Ihre echte kleine Schwester Sie mag, beweist das,
dass Sie kleine Schwestern wirklich moe finden.
¡Tienes moe de hermanitas solo
Tienes moe de hermanitas solo
C’est parce que je suis aimé
de ma vraie sœur
Quando anche la sua sorellina la amerà,
allora avrà trovato il moe delle sorelline.
Ser amado pela irmã de verdade
mostra o seu verdadeiro moe!
Того, кто понял всю прелесть сестёр, 
должна любить даже родная сестра.
