Usotsuki wa Kyuuai no Hajimari

"Please, marry me." My coworker, the person I hate the most in this whole world, suddenly confesses his love to me, but doesn't realize that I'm Haruno Tsumugi...! Tsumugi, who is the lowest performer in sales at her company, is constantly stressed out by her good-looking, top-performing coworker, Atsushi Honke, who is equally aggravated by her inability to do her job. Why is someone as hard-working as me at the bottom, while a game-obsessed slacker like him gets it all...?! One day, she's lending a hand at her dad's drag bar, wearing her usual disguise, and serving customers, when he happens to come in for a drink! Thus begins this love story of misunderstanding born of lies and revenge! (Source: Manga Plaza)
