Don't they all feel too superficial? That's why they each represent a single sense out of the five senses. It's kind of hard to imagine any of these relationships working out at all, especially with how our MC only thinks about the horny and seems to want a girlfriend out of desperation rather than actually feeling a deep connection with any of the girls. It's like she wants to date for the sake of having someone to date and at the same time overwrite whatever feelings still linger from her first love. Likewise, all the girls seem to like MC for the sake of the story, but I have yet to see a reason to why any of them would be attracted to her, outside of their "five sense pick." And now the original GF seems to actually have genuine feelings for her, but for some reason she just wont admit to it, and it seems like she is "fake" dating that one otaku guy. Is it a family issue? I guess we have to wait to find out. I don't really see where any of this is going, but hey, we've gotten this far right? Might as well see how far we can go with this tale.
