Rei also remembers Takamura, and feeling something akin to fate, Takamura once again begins to harbor a faint feelings for him. However, when Takamura witnesses Rei entering a hotel with a man after class, Takamura is surprised and asks him about it. Rei nonchalantly replies that the guy was a sex friend, and Rei's next words are: "I have no idea what it means to fall in love with someone"...?
