yay ! he's speaking up to her. go kuze kun

I also love Kuze-kun- I ship them

 

[PsychoTheRabbit]

Well, shes been with Kuze longer and dont seem to be sway by him. Im pretty certain she'll say something like "i never thought about u that way". Unless it goes in the "maybe i can forget him this way" direction. Thats a pretty early development... but then again, she was already thinking of her wedding dress with Watari.
The only thing i can say for sure is that Shiomi needs her mom back soon. Shes way too insecure and a bit unstable to be left alone like this.
