Any novel series that's just light-hearted, cute, or slice-of-life like Kuma Kuma, Death March, even something like The Dao of Magic I consider just a light hearted lax read due to the chill and worryfree nature of it all. I'd prefer an active novel with lots of chapters already. Just something not sad or dark or with any real problem or conflict. It can be NU or RRL(tho I've probably read all the ones on NU already check my reading list) even an original or lnmtl. I would like a novel, but anime and manga are fine too.
read something on oniichan yamete there're quite a lot of light hearted one anything else would be some slice of life or food focused novel like http://www.novelupdates.com/series/...o-talk-to-a-loner-like-me-during-lunch-break/ http://www.novelupdates.com/series/the-other-world-dining-hall/ http://www.novelupdates.com/series/the-guilds-cheat-receptionist/ http://www.novelupdates.com/series/takarakuji-de-40-oku-atattandakedo-isekai-ni-ijuu-suru/

A lighthearted twist on heroic summoning. It's a little dark in some concepts, but the rest keeps it lighthearted. Yuusha Yori Saikyouna Kuro Kishi
