My Daughter, Geum Sa-Wol - Season 1 (2015)

The genius architect Geum Sa Wol was born from Deuk Ye and Min Ho's one-time extramarital affair. She is a cheerful soul who sees the bright side of things when everyone else thinks the worst. Her fate and Hye Sang's fate get intertwined when their birth parents abandon them at the orphanage on the same day. Hye Sang is Sa Wol's best friend and her biggest rival from their days at the orphanage, and she's also a coy-looking fox who is out to get everything she wants. Deuk Ye sponsors Hye Sang, thinking she's her daughter, and Hye Sang is soon adopted by Sa Wol's biological father, Min Ho. Even in the whirlwind of complexly intertwined relationships, Sa Wol perseveres, builds the house of her dreams, and falls in love with Chan Bin, who is Deuk Ye's son on paper. Everyone wishes to move past jealousy and resentment and go back to being complete, happy families through the beautiful act of building houses.
