An Insincere Idol's Blank Slate

Since we are on the topic of idol manhwa. I am recommending An Insincere Idol's Blank Slate. I'm still reading this, but I'm already hooked. The concept is really fun. An arrogant idol gets sent back to his debut days and has to earn back his "original intentions" through a system. It's funny, chaotic, and has me wanting to keep reading. Has anyone else read this? No spoilers, please!
