I've seen the original book, but i think i like the Visual novel version better. It feels like the full Thriller conversion :).
(Spoiler Below)
But, i simply don’t like the MC in both versions. They gave me this 'unstable and switchy' vibes since the start, and i noticed They always lost their consistency when executing their plans. They want to gain their trusts, but insulted them right after being compliant. I actually expecting the calculated and can-hide-emotions-well type of MC in that one, so the escape ending would feel satisfying, but well...
That aside, i actually love all the boys -including Hiroko and Kenzan-. I think most of the guys turned messed up like that because of their childhood memories. The most heartbreaking individual is Alex, to be honest. He's not loved by his mom, and.. she's a sadist when it comes to Alex. Sorry not sorry, but i kinda blame the mom for Alex's behavior 😂.
And last, the most lovable thing in this is everyone has realistic personalities here. Even Mc is not 'fully angelic' and did something bad in their past. And the boys, though Yandere, they simply wouldn't resort to violence if the mc not violent too. Also the Twins, they're good people at heart, but when they romantically attracted to someone... my goodness. But this is what hooked me with this VN the most :D.
