Hey!
I forgot about the title of this manhwa where black hair MC girl was born on 30 Oct and her male best friend was on 1 Nov so they have a joint birthday party on 31 Oct. But, male best friend's GF got jealous and asked MC to not attend it. So, she have a date with her famous blond psychopath sunbae in college on 31 Oct instead...

Big thanks in advance....
