Koibito Aika to Moto Kare ~Futatabi Ano Otoko ni Dakare Kairaku ni Iki Kuruu Ai Suru Kanojo

Synopsis

The protagonist, Akito Akishima, has a girlfriend named Aika Shiroyama. When they worked at the same company, Akito had feelings for Aika, but he gave up on her because she already had a boyfriend. However, after hearing rumors that she had broken up with her boyfriend, Akito made a desperate effort to win her over. Eventually, she agreed to go out with him.

After that, Akito changed jobs and moved to a different company, where he was content with his life, spending his days off happily with Aika. He was even considering proposing to her and starting a married life together.

One day, there was a major personnel reshuffle at Aika’s company, and he learned that her ex-boyfriend, Yuma Mitaka, had returned and was now working alongside her. Even so, he told himself that Aiika’s relationship with that man was a thing of the past and that he wouldn’t let it bother him. However, he happened to see the two of them walking together in town. When he asked her about it, she told him they were just there for work and that nothing was going on, so Akihito chose to believe her.

After that, they went several days without seeing each other due to their busy work schedules, and even when they did meet occasionally, Akihito began to sense a slight distance between them.

What had been happening between Aika and her ex-boyfriend during that time…? Those events would gradually change the dynamics of Aika’s relationship with her “boyfriend” and her “ex-boyfriend”
