Loved the first 200 chapters or so. At around this point, the story nose-dives and the author overuses sexual assault. Except for the initial FMC, every other love interest assaults the MC. The villain's grand plans are to drug people with a drink so that they can attempt to r*pe them. The only redeeming quality during these chapters were the interactions between the MC and FMC's but even that was cut short with an abrupt time-skip/ending.
I'd say, up to the point where MC and 1st FMC get together, I'd rate it a 4.5 as I really enjoyed the build-up. After the other FMC's start scheming, I'd give it a 2.
