Rei is kinda genius. She either lied or told truth basically about herself. But it put a thought in the dudes head. Dudes kinda dense, he rizzes up girls without even realising he is doing so, and now when he goes around and basically ask them girl if he is a detable material in their eyes, he makes them realise one by one that they kinda already have some feelings for him.
Now the question is - will they just accept it and jump his D like a hentai harem, or will there be some jealousy and cat fighting, etc, or they will go after him and he will realise that he likes one of them and it wont be a harem, heck maybe even will choose Rei and get some magical miracle "cure" to make her a corporal living being with actual time clock, so they could fuck, have kids and get old together?
