Yaaaasssssss!!!!! Finally another rare gem where it's the other way around and the female is finally in the lead for sex in a het webtoon!!!!!! So refreshing!!!! Fyi, there's also another webtoon called 'Sadistic Beauty' with a strong-willed female mc (also a "noona" lol) like this one here BUT the one in Sadistic Beauty is actually a sadistic type. ;) (judging from the title no surprise xD) whereas the noona here is more of the tease type.
