I'm looking for an enjoyable innocent or dense MALE mc who comes off as cute without being annoying or weak. There has to be romance else What's the point of him being dense? No yaoi please, dom/sub play stories, or genderbender. I've read Second Coming of Gluttony, To Be a Power in the Shadows, with this ring, I’m the Evil Lord of an Intergalactic Empire, the novel's extra, and most popular stuff on NU with dense protagonists. I also don't mind fanfics or anything from other sites. Thankyou~
https://www.novelupdates.com/series/is-it-tough-being-a-friend/ Mc kinda dense in the first volume https://www.novelupdates.com/series/my-death-flags-show-no-sign-of-ending/ Mc's too busy preventing his dead flag https://www.novelupdates.com/series/hikaru-ga-chikyuu-ni-itakoro/ Good friendship, and Mc is a Yankee type that start to realize his love at a latter chapter
Not a novel, but your specifications describe this manga too well not to be recommended. Jijyou wo Shiranai Tenkousei ga Guigui Kuru
