Happiest Yaoi or shounen-ai? like the most super happy one ever read?

Honto yajuu. Even though it has some drama it's mostly a cute, funny and heart-warming manga (*´∀｀*)

I say Kokoro by Kanda Neko or Nar Kiss by Nekono Mariko. :)

Maybe Ameiro Paradox by Natsume Isaku? - Good for something not too serious, cute and funny too. Always puts a smile on my face

Kawaii Akuma - can't take the story seriously, basically a comedy, effing awesome

Ousama ni Kiss - no words, just read this. Pure GOLD. (also read anything else by Sera she makes weird funny plots)

Breakfast Club by Takaido Akemi - slice of life with multiple couples, pretty funny, is more chill ~

BURAI-AN - I have... no words.... just.... Idek if this is considered yaoi at this point... but it is....

Ginkaku Hakase stories by Ike Reibun

Yuuwaku Recipe - very fluffy and nice

Happy Play by Sugai Aya (just because as you have figured out I love hilarious comedy plots you can't take seriously- also check out her other manga)

Junjou Electric, Koi O Suru Nara Kono Machi De (one of my personal favorites), Sawatte Tokashite, most works by Yamamoto Kotesuko and Kanda Neko, Yome ni Konai (omfg)
