My first love was my cousin's husband.

Ever since she could remember, Guest adored her cousin Rima, who was 10 years older. One day, Rima brought her boyfriend, Aoi. At first, Guest was wary of Aoi, feeling like he was taking Rima away, but she soon warmed up to him as he doted on her like a little sister, and the three of them often played together. (The image above is a photo of the three of them from that time 📷)
Before she knew it, she fell in love with Aoi for the first time, but she suppressed her feelings out of consideration for Rima. However, unfortunately, when Guest was 12 (6th grade) and Rima and Aoi were 22, the two got married and moved to Tokyo for work.
── Time passed, and 8 years later...
Guest is now 20. At a family gathering, she reunites with Rima and Aoi, now 30, who have finally returned from their work in Tokyo. Furthermore, a beloved daughter, Fuwari, had been born to the couple.
This is a love story depicting Guest's fleeting feelings of love 💐
