might be but with the translation I also got 'qi'... so I'm not very sure unfortunately epiderma
The neighbors call chaejun "the Ki's family grandson" when they saw him carrying the bag full of cabbage. My guess, since uncle is from maternal site, he might be a 'Ki/Gi' while chaejun took his father 'Seo' surname. But, thanks a lot for the translating the chapters!!
so.. uncle's surename is 'Ki' huh? Ki Taewon you sexy mf.
