Have you read "High Clear". It's nice and long and still going. I really enjoy "90 Days" as well. It's very light on the shouldn't ai spectrum and the chapters are short, but it's hilarious and fluffy.
You can try out this list. Consists of completed bl manga. Lighthearted, short and no drama. Enjoy ~~

Opps sorry, i mistakenly replied to you (･o･;)
Lol. It's a-okay. I'm probably going to look at the list myself. (๑•ㅂ•)و✧
Looking for something fluffy easily resolved drama. I love the long dramatic ones but I just need to read something positive like 'our sunny days'
