you know after reading the spoilers it reminds me of a manhwa that i dropped
it was "How Dare you"
it was about a girl who lived with her aunt and needed money.the ML who was a commoner but was wealthy bc he owned a bank and had connections with royalty .
she was the daughter of a princess from a nother country and looked quite diffrent from them so he took her instead of her paying a debt that was left by her father or uncle .
bc she resembled a doll he saw and that doll also resembled the queen ,so he used her to get a higher standing in the social world and so he tasked her to become the princess friend (bc the MC resembled the Queen [the princess mother] it woul be easy for her
oh and the time period is in something like steam punk time? there cars and trains where just made
btw ML had blonde hair i think and FL had black hair and blue eyes
if any one knows the name pls tell me
