They both have a very passionate energetic main character who does their best at a new job. The setting is their workplaces, and in both of them the mc are supervised by a senior with whom despite a rocky start they become friends with. The both of them are also light to watch and have both comedy and emotional moments.
Similar legal drama about two lawyers, male and female leads, handling different cases each episode where things are not always what they seemed at first until they dig in deeper. They get on each other's nerves and bicker at each other from time to time but eventually grow to respect each other. While Ishiko to Haneo is about a small private law firm, Seigi no Se is about a public prosecutor office. Both have same type of chemistry and humour, making it fun and interesting to watch.
