I would say I never expected Hinoka to be the one to take so much of a charge between these two... However Tsukushi always has been a bumbling idiot so it doesn't surprise me at all that she's the one that basically being dragged along by Hinoka lol.
Hinoka is gonna eat Tsukushi alive in the best way possible.
I expect the bath to go as follows: Hinoka putting on her amazingly flirty movies and Tsukushi to just be a giant ball of mush that can't even look at her in the face in fear of seeing boobs.
It's been so long since we got a chapter of this thank you for the translate and upload <3
