Things have been tense between Ryuto and Runa since the culture festival. Ryuto plans to tell Maria they can't be friends anymore, but a shocking incident leads to a discovery that changes everything for Maria, Runa, and Ryuto. 
But there's nothing I can do about the past!
!لكن ليس هناك ما أستطيع فعله بشأن الماضي
Ich kann meine Vergangenheit
einfach nicht löschen.
Pero ¡no puedo enmendar el pasado!
Pero ¡no puedo enmendar el pasado!
On peut pas changer le passé !
Ma non posso cambiare il passato!
Mas não há nada que eu
possa fazer sobre o passado!
Но прошлое ведь уже не изменишь!
