Ataru should just get back with Wanko's voice actress colleague at this point. They seemed fairly compatible and they got along well enough. They could be more than just sex friends.
But then she wouldn't be easy and free drama, even if cheap. Put in a bit of the director meddling and you got some nice, artificial and unneeded angst to spice up this mangas rut. Here's to hope that this will go like the past 90 chapters, in a mature and natural fashion- which was really enjoyable thus far.
