After their expedition was a complete failure Kaneki sent everyone back to their homes and as for Yuuka after she was sent back to her home she immediately went into her room and started crying.
Yuuka: I'm sorry Kaneki, I'm sorry I didn't trust you Kaneki.
Yuuka looked at a mirror then she remembered what Kaneki said.
"You are not Miyu-chan"
Yuuka then said to her reflection.
Yuuka: who are you?
And she began crying and suddenly she heard a voice.
"Why are you crying? It's not that big of a deal I mean you have Ryu-kun after all"
Yuuka: what the?! Who are you?!
She saw herself in front of her but that "Yuuka" didn't seem to care that Kaneki hated her.
"Isn't it obvious? I'm you"
She went from sad to furious after she heard those words.
Yuuka: what are you talking about?! You're not me! Why aren't you sad?! If you're really me you should be sad because we lost our best friend!
"Huh? Why would I? He's just a best friend besides wasn't your dream to be popular?"
Yuuka: what-
"The real reason you wanted to get the relics is so you can be popular but now that you are popular there's no need to get the relics"
Yuuka: !!! That may have been the case but I really do want to find all the relics! It was fun and I had Kaneki on my side!
"But you have someone better than him now"
Yuuka: what?!
"Ryueki Itadori, he is handsome, rich and in general very cool"
Yuuka: he is not better than Kaneki!
"Then why is he the one you talk to more?"
Yuuka: !!!
"Face it just accept reality Kaneki is no longer your best friend and never will be, so just pursue someone better like Ryueki-"
Yuuka: Shut up! You're not me!
Yuuka threw one of her pillows towards the Yuuka in front of her.
Yuuka: I wouldn't just leave my best friend behind!
"Don't lie to yourself the moment you saw Ryueki you fell in love and just left him behind"
Yuuka remembered that moment when she left Kaneki.
Yuuka: even so, I tried to fix my relationship with him!
"C'mon you never even try to talk to him and you even changed the way you talk because you were afraid of being rejected"
Yuuka: !!!
"Just forget Kaneki and the old your old self and just embrace the current you and you'll be happy with Ryueki"
Those words ticked off Yuuka the most.
Yuuka: I can never be happy with him! What?! Forget the old me and Kaneki no way! Kaneki was always on my side no matter what!
Heike: Yuuka?
Heike suddenly appeared.
Yuuka: Hei-chan?
Heike: Heike Keke?
Yuuka: who am I talking to? I'm talking to that-
Yuuka pointed at the wall with no one there.
Yuuka: w-what is happening to me?
Yuuka then went onto her knees.
Yuuka: who am I?
And she touched the cheek that Kaneki slapped.
Heike: Hei...ke...
Heike got close to Yuuka and put herself inside Yuuka's hand.
Yuuka: Hei-chan?
Heike: Kaneki Heike heike.
Yuuka: I... Don't know what to do anymore I don't even know who I am.
Heike: Hei?
Yuuka: I don't know anymore.
Yuuka lied down again on her bed
Heike: hei...
Yuuka: you don't need to be sorry about me Hei-chan, after all this is all my fault.
She then started at the ceiling for a few hours.
Grumble~!
Yuuka: sigh~ I don't even feel like eating.
Heike: Hei! Hei!
Yuuka: Hei-chan... Kaneki hates me now of course I wouldn't feel like eating, I betrayed him and broke our promise, I knew he likes to keep his promise but to think that our first promise was more special to him... It must made him really really sad now that promise is now broken huh?
Heike: Hei..
"Seriously? Lame~ why would he be sad because of some dumb promise"
Yuuka: dammit stop talking.
Heike: Hei?
Yuuka: sorry I wasn't talking to you... I wonder what Kaneki is doing right now? And how am I supposed to face him now?
At the Higanbana residence*
Knock! Knock! Knock!
Miku: Onii-chan! Come out!
Sachi: Kaneki! What's wrong?! Why aren't you responding?!
Sachi and Miku was trying to get Kaneki out of his room.
Shino: I think we should leave him.
Miku: what?! But he's...
Shino: he must be sad right now, not only because his and Yuuka's promise is broken but because he has hurt Yuuka.
Sachi: I understand but if Kaneki feels sad because of that shouldn't he face Yuuka himself?
Shino: he must be afraid of talking to her now.
Miku: but why?
Shino: you two know very well, he doesn't like hurting us and now that he physically hurt Yuuka and said some really harsh stuff, he is probably feeling a lot of guilt right now. I think it's best we leave him alone for now.
Sachi & Miku: ...
Shino: let's go to my place let's eat there.
Miku: sure...
Shino: c'mon let's go.
Shino and Sachi then started walking to leave followed by Miku.
Miku: Onii-chan...
Miku looked back a little then started following again.
In Kaneki's room*
Kaneki: What have I done?
Kaneki was staring at his hand with tears on his eye's.
Kaneki: she probably hate's me now how? I mean I did slap her... With this h-hand
Kaneki was lamenting on what he has done.
Kaneki: BLEURGH!!!!
Kaneki suddenly vommited.
Kaneki: What the? Blood?
Kaneki suddenly vommited blood.
Kaneki then stared at his hand again.
Kaneki: maybe I should remove it, I don't need a body part that hurt my friend after all.
Kaneki was going crazy.
