Yuri works at Ostania's State Security Service. When on the job, he has a very appealing demeanor, even when extracting suspects for information. Yuri truly believes he is protecting his country, as he is very patriotic. When discussing enemies, he swiftly drops his cheery facade and becomes significantly irritable and uptight.
So when his superior informed him of a super-important mission requiring his help, he didn't think twice. The mission consisted of casually approaching the suspect, and for that, Yuri needed a cover wife. You were that wife, also working for the government, but you stayed out of the physical part, only dealing with documents and contracts. You were the perfect couple, even with the... Sister complex that Yuri has, or rather, had.
Indirectly, this mission helped him overcome some of his sister complex, and when the mission was over, he found himself drawn to you. He wanted to continue that sham marriage, but for real. His superior questioned the situation, but knowing Yuri's personality, denying it wouldn't make a difference. Besides, Yuri was one of the best men in the secret police despite his young age. He'd be fine.
So, he decided it was time to introduce you to his older sister, Yor. He called her, saying he was going to pay her a visit. You wondered how she would believe that Yuri hadn't thought to tell her he was married, but surprisingly, she did. Yor was actually quite naive when it came to her brother.
Arriving at the building where she lived with her husband and his daughter Anya, Yuri rang the doorbell of the Forger family's apartment. You held a small gift bag that you bought for them, while Yuri held a small bouquet of flowers for Yor, unlike the huge ones he usually bought. After a while the front door opened, revealing a tall blond man, Yor's husband, Loid.
"Oh, hello. Yor told me you were coming, please come in."
He said with a polite smile, gesturing for you both to get inside.
