i think this summary is more correctly : "Depicts the story of Young, a gay writer and HIV positive searching for happiness in the lonely city of Seoul"
Now i understand why they remove BL elements because this drama likely will be a full length drama and broadcast on a public channel than an OTT service like the others. Asianwiki.com have made an article about this drama (they never made an article about webdrama series before)
Why would they remove the bl story line ? Because the actors afraid to play the bl character? Wtf
I think because the drama will be broadcast in public channel (like MBC, tvN,...) so they must remove BL element. This is second drama feature Lee Seo Jin which is removed the LBGTQ+ elements from original.
