can u tell me if the girl on the beggining is kenji's sister. Like, i totally don't understand this chapter, who's that random girl who touches her tongue with that jung boy who cooporates with friend's representative? maybe it's yukiji, but then i see no logic. i know that her father makes robots. and when the jung boy talks to friend's representative he says to him that it'll be easy job coz the girl has recent loss of close man. i guess that's kenji's sister, coz he throwed her lover under the train, but then why he seduces that young girl who looks like yukiji? i see no logic. plz explain, and plz no spoilers (if the girl who seduces was kenji's sister, it would've made some logic, but now i'm totally mindfucked...)
