I don't know if its a bug but i have 15k money and i wanted to buy new appartament but whenever i go to the real estate place the only choice i have is ''No... i still need some time'' (i did asked ayano to move in with me so because i can't buy new appartament i can't progress). I don't know if its a bug cause im preaty sure at the start of the game i did have a choice to buy new appartament but i was broke
