I think Ren's appearance was too sudden, too. Yeah, I get it; he's the hidden character. But seriously, that doesn't mean you have to introduce him in the very last 10 chapters. He lacked personality. I, as a reader, could not connect with him. His inclusion felt very shoehorn, and he was there just for the sake of a sudden plot twist. There was no buildup, no foreshadowing. The plot twist is just bad.

And because we readers didn't really know Ren, I couldn't sympathise with him when he suddenly accused his own brother's fiancé. Like, I legit kind of hate him. Dude, you've known Serea since she was 10, right? You should've known that she's not a bully; how could you believe in Heroine's words, someone you've known for less than a year? I get it; this is a game world, so you were indirectly influenced by the magic of this game world, but still! Use your brain, okay? Use it! :/

I honestly thought that after Shin (condemner prince) and Serea (villainess) got married early it would be just random fluff all around and eventually getting boring but them preparing and doing the countermeasures against pink hair heroine (what's her name again? Ringo Blabber? Liner Bubbler? Rintarou Chocobo?) and Shin accidentally sabotaging her encounters with the capture targets, the story was still a good read. The ending was satisfactory, the game's compelling force still managing to make the condemnation event happen in a different way but was resolved cleanly because of all the groundwork Shin and Serea laid out, and the two of them live happily ever after.
