I don't know if it's what you want. It's a complicated story, but I adore the mangaka.
Hello guys! I've read a lot of yaoi and shounen ai mangas that end in polyamorous relationships lately. While I still prefer traditional monogamous relationships, there are some poly stories that I liked. However, I was just wondering if you guys have read a yaoi/shounen ai manga that starts with a polyamorous relationship and ends with one of them leaving the relationship? I'm just curious if there are mangas that exist with this plot. Thanks!
