Help me find the manga pls!!

Ok so it's a bl where the seme has a work image where he wears glasses has his hair down and is basically "gloomy" but in his private life he is really hot and sleeps with men ig. The Uke sleeps with him but if I remember correctly he doesn't know it's his coworker at first but later on finds out. The very last thing I remember in this manga was that they all went to a work trip(???) and the seme actually goes to the ukes room as his hot self and ppl noticed that a hot men went into the boss's room
