Aaaand this got posted . Again . <| sep |> it ' s just a tingling there . Even Koyomi feels a little jealous I ' m sure , when she talks about her fatherHe does , its natural and its ok to feel that way . But he is in control of his feelings . The same can be said about Senjougahara feeling jealousy about how much koyomi loves and admires Hanekawa . And as a boyfriend , it ' s only natural , he wants to be her only male lovestruck . Yup its natural thats why he doesn ' t repress this emotion like the old hanekawa would , he feels it , then he controls it . He even says that he won ' t let this emotion ruin his date . the way she talked about him in Neko Shiro , with Hanekawa , what els could you gather from it ? How about the way koyomi talked about his sisters in hanamonogatari ? Its just senjougahara teasing with the truth again , she does feel some sexual attraction to his manly man father but thats it . She gets excited if she sleeps in father ' s bed . That seemed to me just like when Hanekawa slept in Koyomi ' s bed , even if it ' s a joke , which I doubt it was . Lets assume she wasn ' t joking . I get excited when I visit some cousins and get to be alone with them because they are pretty . But thats it . Improper thoughs ! improper relation . The same can be said the otherway around . From nadeko perspective before nadeko medua she though her relationship with koyomi is totally pure , just love and nothing else koyomi never even looked at her in a sexual manner and she was not afraid of him lifting her skirt so maybe in her mind they had some intimacy relationship . But their actual relationship is the opposite . From kaiki perspective , senjougahara is in love with him but when they are together senjougahara reverts to her former self and lies , deceipts , controls and treatens . She even tailed him everyday to know his wereabouts and possibly she is the reason why koyomi arrived at that precise moment after the confrontation . So overall , yes senjougahara does all that and yes koyomi feel somewhat uncomfortable about it . But thats it on both sides . Both understand what they do and control it .
