“Aikotoba” is a very popular matchmaking app where you can find your soulmate just by filling out a short questionnaire. With a stable job as an office worker, Takumi was introduced to this app by a friend. He was matched with a girl named ‘Yozora’ with a 99% compatibility rating, and he indeed fell in love with her.

At that time, he was to travel to Sendai for work, so he decided to meet ‘Yozora’ in person. He waited for her to appear by the gates at Sendai Station with both excitement and apprehension. However, when ‘Yozora’ appeared, she was shocked and her eyes welled up with tears immediately upon seeing him.

“Onii…chan…?”

It was the voice of his imouto Uzuki, who he had not seen in seven years.
