Looking for manhwa

Don't remember much but its about an office lady asking her manager out. She did it unconsciously bcs shee keep thinking abput what her friwnd said. The manager look like the nerdy type. But when they met again at a wedding, the manager look very smart and stylish. At a compamy dinner, they play a game to pick a partner n she was chosen by the manager n this other guy but she chose the manager n they went on a date. He is actually the president/ceo of the company n liked her since long ago but dunno how to approach her.
