Sweet something

I forgot the name of it but i know it started with the word sweet. The main characters consist of a guy that mistakes a man for a girl and chases after him in a club/bar. In the same chapter the sister finds this guy and finds him hot, and we get some rivalry. One thing to know is that the 'top' is the one mistaken for a girl. And basically the 'bottom' would appear as a top. I will say again that the name of this manhwa(idk?) starts with sweet.
