Game seems bugged, stuck and can't make any progress anymore it seems, only thing I can do is just "chat" with the girls, which is annoying because half the time it just fails, so the game is just wasting my time and im not able to do anything. speaking of which, please just remove the dumb "failed to chat" from talking with the girls.
If you’re talking about Season 1, there shouldn’t be any bugs there. The game has been completed many times by me and other players. You should follow the events marked with the heart icon, increase your relationships with the girls, and explore different locations to progress the story. It’s also important to buy transportation.
In Season 2, there are hints for every stage of each quest — both for the girls’ quests and the main storyline.
