There's still hope.

"What happened, Ritsu-nee?"

Ritsu is just staring at Aiko and not answering her question. Aiko looks at me and I just nod at her to tell her to follow what Ritsu wants. Aiko is still hesitant because Ritsu hasn't given her a reason why but then she walks toward Ritsu. Ritsu doesn't pay any attention to me at all, she even doesn't even take a glimpse at me. They both leave the room and I follow them from behind, Arata and Kureha are staring at Ritsu then they both look at me with curiosity, I just shake my head because I have no idea what happened to her as well.
