You don't lose much Kotori, i seriously hate when in a couple there one who doesn't want the other to had interactions with any girls because of a pathologic jealousy. I don't like Yuki, she seem to be a serious pain in the a*s jealous GF.
I liked this chapter's story more than the previous. The first chapter had better visuals, though. Like some others, I had difficulty identifying who was who in this one.
