I don't think there is a way to get hardstuck without being able to progress and having to restart. But there are some very especific roadblocks that the game throws at you. Whenever you feel like there is absolutely no way forward, you have to try weird things like going back to sleep after going to the dormitory (without talking to anyone), or calling someone that wasnt in your contact list. And to make things worse, some of these things only trigger in especific days of the week and time of day. But if you feel too frustrated take a look at the wiki
If you want some gameplay tips tho:
don't kiss Chika before the class beach episode
