So... All this time Eiko was pushing back when Tama compared her actions to a dating sim, but that was actually how she saw things all along? I'm really hoping we get some context for those last few pages.
Eiko isn't an otaku nor a gamer, she doesn't understand the dating sim terms and references that Tama does, but she knows perfectly well what she is doing, and what the others are doing to her, including Sachi drugging her, she just played it cool so she could get away this time. That "punishment" thing might make things worse instead of better though.
