Wait you watched the ENTIRE first half thinking two characters were the same person? That is wild. I'm trying to picture episode 7 you sitting there like "huh, this guy sure does get around" while the plot is happening to two totally different people. Honestly the fact that you made it to episode 7 before figuring it out is kind of impressive in a painful way. The betrayal angle makes it so much worse too because that's the whole point of those shows, you have to know who is backstabbing who. I'd say just rewatch the sub now that you know who everyone is, it'll feel like a brand new show and you already put in the work. Or watch the dub since you liked it, no shame in that, at least you'll actually follow the story this time.

Saw a nurse blogger do the same, only log work days.

Same thing happened to me with the 2 inch strips for my 6 foot privacy fence. I counted 12 boxes thinking that would cover around 1100 nails and I came up short by almost 40. I even dumped out the last box on my workbench and lined them up in rows of ten to be sure. The strips were mostly full but a couple had gaps where nails were missing, like the factory skipped a few spots. Lowes swapped the boxes but it still cost me a trip and half a day of work.
