Ijiwaru Joushi no Amai Kekkon Keikaku

Look, it's not like Azusa doesn't want to get married. She's a wedding planner, after all, and in spite of her boss's biting sarcasm, she actually finds a lot of comfort in her job. Her boyfriend of five years, Ayumu, just hasn't really brought up the conversation, that's all. Or at least, that's what Azusa thinks, until she catches Ayumu having an affair! Though usually extremely unpleasant, Azusa's handsome boss, Kiryu, offers her sudden and uncharacteristic kindness: "If you don't get married, then I'll step in." What's that supposed to mean?! The sudden tension between Kiryu's usual offensive nature and his sweet words has Azusa wrapped around his little finger, and she's not sure if she can get away... or even wants to?!
