So I see this manga from my fyp recommendations but I forgot to save the video.

This is a BL manga, and I think the manga is based on a real gay couple from Japan, and the end they both married I'm so sorry I can't remember anything else

I think someone said that the main plot of the manga about how hard it is being gay in Japan and the acceptence towards gay couples, but I'm not sure
