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'm not going to let him rework 
the ultimate little sister.
Ich lasse ihn diese perfekte kleine Schwester
nicht überarbeiten.
Non gli permetterò di rivisitare
il massimo esempio di sorellina!
Eu não vou deixar ele mudar aquela
história fantástica de irmãzinha!
Я не дам ему извратить 
лучшую сестрёнку в мире!
