errr... I even not sure that this is the last episode from season 1.... there should be another episode next week... no preview about the second season, right? (well, it's JC Staff style for not giving any clue about season)
overall, just give this 9/10..... I don't read the novel seriously so I think the adaptation is "good"
mentioning Kana's name since ep 11 maybe just another strategy to give some curiosity to the watcher
