Some of these might fit your requirements. However it’s not just BL and there are some J-dramas that you shouldn’t skip.
The New Recruit/Employee
thx I've heard of the drama was good
Cool! I didn't know about a few of these so I'll check them out
thanks for the list. I see some that look interesting
Are there any lists for BLs that were/will be adapted into kdramas? Looking for full color manhwa. Thx
