Thanks for the TL.
I definitely expected Volume 5 to at least have the start of the trip, but looking at Volume 7's cover, maybe Volume 6 will have the full leadup, with the trip starting and then bleeding into volume 7?
I very much hope we continue to avoid the melodrama & usual formulaic tropes of romcom manga, though. No misunderstandings or arguments borne of lack of communication - these two have been amazing in navigating all of this, even as they individually grapple with their feelings and haven't spoken aloud to one another yet (though everyone around them already gets it, of course).
But if this goes the distance with no contrived drama that feels inserted purely to stretch the narrative, I think it might end up being one of the better romance titles in recent memory.
