GENIUS Spy accidentally marries a Heartless Assassin

Lloyd, also known as Twilight, is an exceptional spy for West Dallas, honed from a challenging upbringing. His skills in combat, speed, and intellect are matched only by his ability to blend in and manipulate situations. His latest mission involves infiltrating the opposing party in Austinia, suspected of assassinating a diplomat and threatening peace with West Allis. Lloyd's plan requires him to pose as a family man, adopting a telepathic girl named Anya to gain access to Eden College, where his target, Donovan Desmond, attends social gatherings. Lloyd's cover is blown when Anya inadvertently sends a message to Austinia's intelligence service, leading to a confrontation and the need for quick thinking to maintain their mission.

After his cover is compromised, Lloyd must adapt quickly to protect Anya and continue his mission. He fakes a family with Anya, who is initially excited about the situation but later realizes the temporary nature of their relationship. Lloyd's mission becomes more complex when he is forced to find a wife to pass the interview stage at Eden College. He chooses Yo, a woman with a mysterious background who is also an assassin. Despite the fake arrangement, Anya and Yo develop a bond, and Lloyd's mission becomes intertwined with the well-being of this makeshift family.

Lloyd, Anya, and Yo engage in activities to appear as an upper-class family to pass the Eden College interview. Despite their efforts, they struggle to fit the mold. Lloyd is forced to prepare for every possible question the interviewer might ask. During a day out as a family, they inadvertently reveal their true identities, with Anya using her telepathy and Yo her assassin skills. Despite the setbacks, they are praised by a grateful grandmother, which boosts Lloyd's morale. However, the day of the interview brings more challenges, including intrusive questions from one of the interviewers, Swan, who undermines the family's unity.

The interview stage is a test of the family's unity and composure. Lloyd and Yo provide compelling answers, but Swan's provocative questions create tension. Anya's response to a difficult question about her parents earns her 100 points, leading to a breakdown. Lloyd loses his composure, causing further issues. However, the family's genuine care for each other impresses the other interviewers. Despite the challenges, they are hopeful for a positive outcome. When they don't find Anya's name on the initial list of successful applicants, they are disheartened, but a last-minute opportunity arises when Anya is added to the list of successful candidates.

To celebrate Anya's acceptance into Eden College, Lloyd arranges a day at a castle, involving top agents in a staged rescue mission to fulfill Anya's wish. The event is a success, but it alerts Lloyd and Anya to the increasing risk of kidnappings at Eden College. When Anya's school uniform is ready, Lloyd asks Yo to collect it, but she is abducted by four people. Yo manages to scare them off, but the incident highlights the danger that Anya faces. On the orientation day, Anya is bullied by her classmates due to her father's profession, but she stands up for herself and her friend Becky when pushed too far.

Yo's struggle with her role as a mother and wife is evident when she seeks advice from her colleagues. Meanwhile, Lloyd becomes increasingly suspicious of Yo's involvement with the secret police, leading him to plant a listening device on her. When Yo is confronted by agents posing as secret police, she manages to deflect their questions and maintain her cover. Lloyd, disguised as one of the agents, realizes his suspicions were misplaced, and Yo's fierce protection of her family convinces him of her loyalty. However, the incident leaves Lloyd on high alert, aware that Yo's brother Yuri is also in the secret police.

After the confrontation with the fake secret police, Yo feels relieved but also guilty for not being able to fulfill her role as a mother and wife. Lloyd reassures her that it's natural to want to improve and that patience is key. Anya, sensing the tension between her parents, urges them to get along. Meanwhile, Yuri's presence in the secret police is a concern for Lloyd, who suspects Yo might also be involved. When Yo is questioned by the real secret police, she manages to maintain her cover, but Lloyd's doubts about her loyalty persist. Anya's school life takes a turn when she saves a fellow student, earning her the first Stella award and improving her image at school. She hopes this will lead to an invitation to Damien's house, aligning with her father's mission objectives.
