The main character of To Be a Power in the Shadows! is quite shameless when in his "ordinary" disguise. Also in his shadow mode, how he just randomly makes up stories to mislead people is quite shameless now that I think about it. Just started (and caught up) reading the manga of Lonely Attack on the Different World a few minutes ago, and this MC also seems to be a bit shameless in a hilarious way. There is a lot of shamelessness going on in this novel, Why Not Soar Your Majesty. Do try it out. It's the most funniest novel I've read on this site. Although not very much, there are a few brilliant displays of shamelessness in The King’s Avatar. Some of the best I've ever seen so I recommend you try that out. (It's one of the best novels on this site too, it's a must read if you're an avid reader on NU or like Chinese novels. It's completed but the chapters are not available here for licencing reasons, so I recommend googling the rest of the 1000+ chapters.) And finally History’s Strongest Senior Brother. Like the previous one, there's not that many displays of shamelessness, but the ones that are present are kinda ingenious so I really like those moments.
Unruly Phoenix Xiaoyao The main character has a completely different mindset from everyone else and this translates to shamelessness
