Upon first playing the game, you can't enter one specific heroine route and must first go through, what I'll refer to in this guide, the common route.

• Day 1 and 2 are pretty linear and don't have any dialogue choices, so I won't go over them.
  
• The character event tables below for day 3, 4 and 5 also apply to heroine routes with no differences.
  
• A "✧" signifies that the event is empty (doesn't feature any character).
  
• Keep in mind that you can only visit a select location once during every day.

Choice
Enoch : if I may ask... what's your honest opinion of my sister?
I definitely wasn’t excepting that, but my answer quickly springs to mind.

• I like her -> unlocks the Training Grounds
  
• I'm not sure yet -> unlocks the Library
  
• Do you have a thing for her? -> unlocks the Infirmary

The Flower Garden, Stairs, and Workplace are available with every choice.



Starting with this day, side events featuring side characters appear. More or less all of them feature 3 dialogue choices - you can only pick 2 of them everytime, so make a save before picking the 2nd question if you'd like to read every dialogue line. These events and the choices you make in them don't affect the route you will get either, but I strongly recommend checking them alongside the associated route for additional worldbuilding facts.
Note : having seen the Flower Garden/Stairs event of the day prior is required for Clione to appear in the Stairs events of day 4 and 5 (otherwise, her events don't trigger at all).

Choice
The one thing that’s been pushing me forward the most has been...

• My curiosity towards the unknown -> unlocks the Workplace and Library
  
• My sense of inferiority because of how powerless I feel -> unlocks the Training Grounds and Infirmary

The Flower Garden and Stairs are available with both choices.


Choice
What should I do with this problem?

• I should talk about it with someone else -> unlocks the Training Grounds and Infirmary
  
• I don’t want to worry anyone else with this -> unlocks the Library
  
• I want to solve it myself -> unlocks the Workplace

As always, the Flower Garden and Stairs are available with every choice.


You will get access to the day 6 event of the heroine you spent the more time with, but won't actually be able to enter her route.
However, the day 6 events of Maya and Haku in the common route are rather different from the day 6 events from their respective routes, so I recommend checking both versions of these two events.


You can only go to one place on this day. Neither event have a specific impact on the following days.

"Will you promise to stay with me until the sun rises?" -> Yes
(The save function gets disabled shortly after this single selection choice, so I recommend making a save file around here in order to see both endings easily)

Choice

• I love Maya -> common route path 1
  
• I hate Maya -> common route end B

If you went with common route path 1 :
"Let's be happy together, forever..."

• Say yes -> common route end A
  
• Say no -> common route end B

Once you clear the game for the first time, you now get access to Paradise! (= heroine routes)

Opening : "Let's go to paradise." -> yes
Associated location : Flower Garden
The latter is available with every dialogue choice on day 3-5, so what you pick doesn't matter as long as you select it as your first location visit of the day.

Day 6 -> Flower Garden
This day has no choices, but its event is different from Maya's day 6 event in the common route.

Day 7

• Stop her -> Maya route side A
  
• Let her pass -> Maya route side B

I recommend making a save file before this choice, as both sides of the route are quite different.

Tip : once you saw both sides of the route and have cleared Haku's route, go back to the end of day 5 (Paradise) to unlock a new minor dialogue choice.

Opening : "Let's go to paradise." -> yes
Associated location : Training Grounds

Day 3
"If I may ask... What's your honest opinion of my sister?"
I definitely wasn't excepting that, but my answer quickly springs to mind.
Pick "I like her" -> Training Grounds

Day 4

Pick "My sense of inferiority because of how powerless I feel" -> Training Grounds as 1st or 2nd location visit

Day 5

Pick "My curiosity towards the unknown" -> Library as 2nd or 3rd location visit

Associated location : Stairs

Day 3
"If I may ask... What's your honest opinion of my sister?"
I definitely wasn't excepting that, but my answer quickly springs to mind.
Pick "I'm not sure yet" -> Stairs as 1st location visit

Requirement : having cleared Maya route side B beforehand
Associated location : Workplace

Day 3
"If I may ask... What's your honest opinion of my sister?"
I definitely wasn't excepting that, but my answer quickly springs to mind.
Pick "Do you have a thing for her?" -> Workplace as 3rd location visit

Day 4
The one thing that has been pushing me forward the most has been...
Pick "My curiosity towards the unknown" -> Workplace as 3rd location visit

Day 5
What should I do about this problem?
Pick "I want to solve it myself" -> Workplace as 1st location visit

Day 6 -> Workplace
This day has no choices, but like Maya's day 6 event being different in the common route and in a Paradise run, Haku's day 6 event presents some differences.

Day 7

• Let her pass
  
• Don't sleep
  
• The reason why I work so hard is that... -> I'm doing it for you

Day 8

• I can't sleep yet...
  
• The incident in question has long since passed, and I honestly don't really want to talk about it... -> Answer honestly

Day 9

• Don't sleep
  
• Is something bothering me? -> Yes

Day 10
Which path do I choose? -> Don't give up hope

Day 11
It was an outrageous story, and yet it was clear she meant every word that came from her mouth...

• Believe her -> Haku route end A
  
• Don't believe her -> Haku route end B

In the common/non-Paradise route, you can trigger a short hidden event by purposefully ignoring every heroine event on day 3-5. This can be done with this method :

• Day 3 : pick "Do you have a thing for her?" -> go to the Workplace -> Flower Garden -> Stairs
  
• Day 4 : pick "My curiosity towards the unknown" -> go to the Library -> Workplace -> Stairs
  
• Day 5 : pick "I want to solve it myself" -> go to the Stairs -> Workplace

(Note : the event you'll get on day 6 by doing this is Maya's.)

Once you clear a route and have seen its ending, you can get a "true" good ending by re-playing a route (in Paradise mode) until a specific point where a new dialogue choice will appear.
For Grette and Rose, this happens in the day 6 event of their respective routes ; Arne's is on day 10 ; Clione's happens during her day 5 event. For Maya, a new dialogue choice will appear at the end of day 5 once you have seen both sides of her route and have cleared Haku's route.
Seeing a route's good ending also unlocks a new title screen illustration, which you can set in the Gallery -> Background section on the title screen. ✧
