Zero drama✓ Zero tragedy✓ Zero dog blood✓
Feel good BL, mostly danmei, and modern or future settings (I removed the historical ones because they're already in my historical danmei rec list). Includes shounen ai, yaoi, and BL with smut. Plot has little angst, since I don't like novels full of misunderstandings and dog blood. There were too many titles to sort by personal preference so they're sorted in alphabetical order. I personally read each and every one; I didn't drop any of them.

I realized I left out a few good ones in this list so I created a part 2: https://www.novelupdates.com/viewlist/87244/
