Ryoma Shiba is a hardworking ice cold no nonsense lawyer who doesn’t have anything in life that interests him apart from becoming the guardian of the law. He is so antisocial that no one wants to work as his partner lawyer. It’s his hundredth time to finally find one but Shiba isn’t bothered as he believes he can handle the whole work work himself. But one night at a bar, he mistakenly runs into a handsome man while leaving the restroom. The man Haruto is injured and Shiba gives him his expensive handkerchief to clean up the wound. But when Haruto thanks him with such a charming flirty smile, Shiba is flabbergasted and for the first time feels something.
He is unable to forget Haruto and keeps thinking of him such that even his potted plants can’t help him so he goes camping to calm himself only to run into Haruto at the site. Apparently, he was visiting someone and happened to see him. Haruto’s constant flirting flusters Shiba. He even cooks him exquisite meat. He tells Shiba that they will meet each other later. Afterwards, he leaves, making Shiba confused about who he is.
That night, Shiba is shocked when Ryoma enters his tent, having escaped from a woman. Shiba lies to the woman that he had never seen him and she leaves. To Shiba’s reluctance, he allows Haruto to sleep in his tent believing he owes him for injuring him and letting him cook for him. But when he wakes up, Haruto is gone, along with his luxury car but he is shocked to find Haruto at his home offering to live with him and become his 100th partner or risk him uploading his naked video on his social media account.
The epilogue shows the woman from earlier complaining to Shiba’s colleague Kazama about Haruto scamming her of her money.
In the next episode, Haruto agrees to let Shiba live with him as long as he keeps to his ten rules but Haruto finds the last rule challenging; not talking to his plants. Shiba watches mesmerized at how Shiba looks while fondling his plants.
After a long and tiring day at work, Shiba returns home surprised to find that Haruto had cooked for him. The foods are coincidentally his favorite dishes and tastes so good. Of course, Shiba won’t mention it to Haruto. He is shaken when Haruto suddenly enters his study at night where he is pondering over a case. He is wearing only a boxer and Shiba who is startled warns him not to go around naked but Haruto reminds him of his own naked video. He offers to help him with his new case and promises to delete the video and leave if he doesn’t prove himself useful but Shiba finds him mysterious and Haruto adds that it will be boring if he knows everything about him.
However, when he finds out that Haruto is a scammer from his colleague Kazama, he is determined to kick him out but decides to do so discreetly. While at the bar, Haruto texts him that he has news for him. When he returns home, Haruto gives him a wiretapped recording and surprises him by knowing legal terms. Despite his suspicions, he allows him to become his partner, determined to figure out if he can be useful or not. But then, he starts having lustful thoughts while staring at Haruto. The latter quickly notices but the tension eases when Haruto shows Shiba the expenses he accrued while fishing for information. It’s a lot and Shiba warns him to take his permission if it exceeds 50,000 yen.
Once again, Shiba enjoys Haruto’s delicious meals but panics when Haruto suddenly seduces him, asking to be his first lover.
