Manga Like A Guide to Reincarnation

Sentinel: Hey, you know what? I got here through reincarnation. Guide: Oh... it was transmigration for me. We're in the fictional world of a novel where you're the villain, and I'm the cannon fodder. Here, have a look. Sentinel: (Skimming through) Oh, so that's how my second life ended... Psh, Planet X's rebels were utter trash, and Y Nation's government was so weak. Did the leader of Planet Z's bandit gang go soft in the head? How could he become traitor for the sake of love? Guide: You've been reincarnated more than once? Wow! Sentinel: Yeah, I'm in my third lifetime now. I never thought I'd get reincarnated again and be lucky enough to meet you... Guide: So what if you meet me? Sentinel: Now that I've met you, you've inspired me... to clean up my act. (Source: Bilibili Comics)
