I haven't touched this game since 1.3. There's quite a bit in the game but you really have to go out of your way to find it. Namely, getting condoms to engage with stuff in the hotel, you buy condoms after school hours. But in terms of what is new right away, you get to go on a date and if you buy wine after getting close enough, you get a dream sequence and some other story related stuff where the MC's muteness comes to bite him. It isn't apparent but, if you are to grind for something, grind working at the gym. Hitting I think it was the 'f' key lets you pass the hour but also travel to the school directly. Though for some confusing reason, I don't know how or why but it is still an issue in which terms referred to for the clothing aren't consistent. Like Daily vs Casual in a few of the quests ask for something very different and you have to make the connection that you're supposed to be in casual or daily. This game is in dire need of an editor for the English side as it's not much of an issue for the native language. Otherwise... you're going to have to wait until the next update comes which you'd have to keep in touch with the patreon or discord.
