ugh

so I'm looking for this webtoon about a CEO and his secretary which used to be college room mates, but the secretary secretly likes the CEO. The secretary is actually trying to pay for his dads medical bills so he works as a singer at a bar during the night. When suddenly the ceo goes to the bar an falls in love with the singer(secretary actually changes his appearance during the night job). This is all I can remember about it , if anyone can help I would be very grateful. (⌒▽⌒)
