If that book relates to there relationship then its likely the ice demon in the title is her maybe telling her through his book that he doesnt love her and feeling depressed and if that's true then her confession of love to Kita is a lie.
I really like the translation and editing but what a shitty mentality that shows on the credits pages...
It's starting to be quite annoying and is ruining the pleasure of reading.
Hoping he will get some soon, maybe then he'll be less frustrated?🤷
I hope we find out what her deal is sooner rather than later. Kita needs to grow some balls and sit her down and find out already. At this rate he'll just end up a giant ball of anxiety wondering.
