Thanks for asking the question. I was just wondering where was merry/serious, then thought maybe it was carefree/farsighted, but that didn't make any sense because when I checked my answers, it had enfp as carefree. I've since looked and found that istp, isfj, entj are also carefree fi/te types. So it's obviously not that.
Thank you for checking for which set it actually is.
(you too, @lungs )
