Thanks to Red from Discord. I followed his guide it get 'Hazuki...?' and 'I Want To Meet You Again'.

You first wanna make sure you are in January, any day basically that the festival is active

When you go to the end of the festival there should be a lady, if you interact with her you can buy what's called a omikuji

You wanna keep buying until you get the bad luck one

Once you do, you'll trigger the event

Make sure to not buy any other once you got the bad luck one

Once you have that step done, what you want to do next is speed up time till its around 20:00, make sure, to make a save file just in case

Then you wanna make your way to the love hotel, go inside, Hazuki should be following you. If not just keep going in and out until she does

Then you want make sure you go to room 101 with her and talk to her

Just like about 2 or 3 times just to make sure, now go ahead and leave the hotel, go straight home

If for some reason, you start looping and it's not letting you advance, just talk to Hazuki again and try to go back to the love hotel, it might loop again for a bit but if you go back to the entrance, that means you are good, now you can do ahead and go home


Once you get home, it's gonna trigger an event and Hazuki will talk to you, once thats done. DONT GO TO SLEEP, very important

Now you'll notice that the time goes beyond 22:00


What you want to do next is keep speeding up time till its 44:44 exactly

Once you have completed the step, go back to the love hotel, and go to room 101, Hazuki should be there, talk to her. And an event triggers once more

At this point you'll get the "I want to meet you again" achievement

Once thats finish, go back home and go to sleep now

Another event triggers and you'll get the last hidden achievement
