I once suggested that it would be interesting if Komori and Kobayashi were related. Kobayashi could be all disgruntled over her voluptuous younger relative. People started replying it was stupid, and no way that could happen.
Now we've seen little sister aged up some recently, and she seems to be developing a bit like her nee-san, but on the last page here she looks a lot like Kobayashi with curves. How could I not think the relation is possible.
