Other than one or two inconsistencies I think it was perfect, Sarah Kim should "win" 9 out of 10 times and she did, if the ending was any different it would've been mediocre.
Couldn't Kang Tae Pung have bought Typhoon trading back if he let Pyo Hyeon Jun sign the declaration of disclosure and then used the promissory note that he found to get the 30% shares and money from Pyo marine merchant?
In it's own aspect this was perfect. Genuinely was so refreshing from the usual dramas, I'd say it's a pallet cleanser for anyone that is burned out from watching dramas.
It definitely deserves a second season.
