in my canon run im going to maintain that the main character and Mina arent good for each other. even taking Ian out of the equation and even as casual sex friends shes clearly investing alot into the main character emotionally and the eventual reveal of what hes been up to at the club would almost certainly going to break her heart if the two of them became closer, unless you lead her down a dark path, the main character even talks about this. Hana is probably going to be my canon choice, her and the main character have good chemistry but she knows what hes going through and what hes doing, she even saw what happened in the most recent challenge, and was okay with it even if she would prefer he didnt have to do it. theres no seedy secrets between the two
future updates should be really exciting though, for all intents and purposes the chains are "off" for Hana and Mina. Mina has her sexual bucket list and Hana is getting more involved with the club. both are easy paths down to finally having sex with them and, if you go for it, probably much kinkier stuff. looking forward to it!
