Man, does this thing take a hard right turn between chapters 1 and 2.
Chapter 1: Silly cute travelogue between a pair of mildly awkward goofs who overcome cultural differences though their shared experience.
Chapter 2: Generic immature new couple WACKY HIJINKS rom-com #54,196
I'm not dropping it after 2 chapters because it deserves enough runway to prove its final direction, but it feels like they sold us a fun concept in chapter 2 then the author panicked when he/she realized they didn't have enough ideas to fill a bunch of chapters after that so they scrambled and made the most cliched, troperrific paint-by-numbers relationship comedy they could.
Honestly, I would've believed that this was a one-shot that won a contest or something to get itself serialized.
