The mom’s name is Lee Suryeon and Rosa is Lee Rosa. From korean surnames, Rosa’s last name should be the dad’s unless if her dad’s surname is Lee. or unless divorced and dropped the name?(not sure)
Also with Rosa being adopted based on the synopsis, it makes sense why her surname is Lee.
Part of me is curious abt the male contraceptive pill, but its a good thing that women arent the only ones to take those. Howeverrrr, thes might be a plot device of something like if ever it doesnt work or something
