I don't understand what you you mean by dirty campaign, i helped koro being elected and I chosed to sit next to her, not having sex with Sophia, and clean the warehouse so what did I do wrong ? (and thank you for this awesome game)
Maybe I'm expressing myself wrong, English is not my native language. In Chapter 1, you can run for class representative election yourself. If you do, you can choose whether to run an honest or dishonest election campaign. And the dishonest one is the dirty one, that's what I mean.
You did well, you should have seen the kiss with Kokoro at the end of the chapter. And now, in the part of the game where you go, when Kokoro tells you that you can't join a club because of Yuri, you should have had the option to ask Kokoro to talk to Yuri for you, thus avoiding her blackmail.
Thank you very much! I'm very glad you like it.
