Okay, but since orcas can only hold their breath underwater for 10-15 minutes on average, Idate has gotta be making frequent and quick trips to the surface.

So, imagine this:

  • Idate flirting with Tatsumiya, when his breath draws near to running out.
  • Idate then giving Tatsumiya a very passionate kiss, with his excuse being it was simply to ‘borrow’ some air from her, as she just stands there flustered and red.
  • Idate then leaving with some suave-y line or something, and Tatsumiya secretly hoping he does it again.
