This guide serves to walk a player through the game and get all of the endings. The heroine's default name is Selene and will be referred to as such when needed.

Chapter 1
Once the player clears at least 1 route, the option to skip Chapter 1 becomes available when starting a new playthrough. Though there are choices in Chapter 1 that affect the Affection stat for each love interest, the stat gains found in Chapter 1 are not needed to unlock any of the endings (I.e. you don't need to get the ~12% Affection available to achieve the 60% or 100% Affection threshold for the achievements/endings because the game contains more than enough choices to raise these points). If you skip Chapter 1, every love interest starts off with 6% Affection.

Dates
Every month, Selene can choose to go on a date with one of the four love interests or the player can press "Skip This Month" to avoid it altogether. The month Selene goes on a date doesn't seem to matter as the game's date scenarios doesn't sync with the calendar (i.e. Selene can go on Date 1 with Iris in September and Date 1 with Eleanor in October).

Affection
The main way the game locks the player into a certain romance path is based on the Affection stat (measured in %) Selene has with a character. Generally, the path is locked after July and the game will prefer the love interest that has the highest affection % as long as it meets a minimum 60% threshold.

???
Each of the love interests has an additional ??? stat that pops up. These choices tend to show up in later months and are related to the bad endings for each love interest. This ??? stat represents something different depending on the love interest being chosen. The conditions for the bad ending for each love interest are outlined in their individual sections.

Cell Phone Texts
There are times during the chapters where Selene's cell phone pops up and the player has to make a choice for the text messages in order for the story to progress. As pointed out by both DataNinja and Sh-Vr, there are some messages that affect Affection and some that don't.

At the end of each month, the player can choose to text one of the four love interests. The choices do not matter and will give a 2% Affection increase for the love interest chosen. These texts can be skipped entirely by clicking on the power button and do not affect the overall outcome of the story.

All of these achievements are automatically unlocked once you clear through that specific chapter.

Soulmate
Complete the first chapter

Internship Secured
Complete the second chapter

Promoted
Complete the fourth chapter

Final Achievement
Congratulations on unlocking all the achievments!

These are choices not locked to a specific love interest and are part of the main story. Choices made can affect one of the love interests Affection or ??? stat. Choices that affect a love interest are labelled as such; otherwise the player can pick anything and it will not affect these stats.

• You must get through Date 10 with ??? at 0%
  
• When prompted between "Hesitate" and "Break Up", choose "Hesitate"

For what it's worth, I skipped Chapter 1 and went on every date with Victoria, picking every choice that would give me Affection and no ??? and skipped Date 11 with no consequences and at 66% Affection. I kept track of my Affection levels with the tracker in the game. The harder part is making sure Affection doesn't go past 70% than ensuring ??? remains at 0%.

Reincarnation
Unlock the true ending

The true ending is unlocked after completing all of the good endings for each of the love interest. For the true ending, I'm not sure if the affection level for a character affects whether you get locked into a romance route or not because the route gets triggered in June and you get locked into a romance route in July/August. You can make any choices you want, but you need to visit the "?" location marked on the map at the specified months in order to unlock it:

• December
  
• February
  
• June

I'll outline what I did to see the true ending, but you should be able to do whatever you want for the "Skip This Month" options and it will still give you the ending as long as you visit the "?" spot in the months listed above.

September

• Skip This Month

October

• Skip This Month

November

• Skip This Month

December

• Click on the "?" location (Unknown Location)

January

• Skip This Month

February

• Click on the "?" location (Unknown Location)
  
• Choice 1: Doesn't Matter

March

• Click on the "?" location (School Campus)
  
• Choice 1: Doesn't Matter
  
• I don't think this scene affects the true ending in any way, but this event has a CG that you otherwise will miss (thank you danadun for pointing this out!).

April

• Click on the "?" location (School Campus)
  
• I don't think this scene affects the true ending in any way.

May

• Skip This Month

June

• Click on the "?" location (Unknown Location)
  
• Choice 1: Doesn't Matter
  
• You are now locked into the true ending

This is a new section with additions based on comments from other users and the guide was updated based on their findings. I wanted to credit them in a separate section entirely.

DataNinja and Sh-Vr both pointed out that some text messages provide Affection increases.

danadun pointed out that 1 missing CG can be found by going to the '?' location in March and tagging along on the date between Megan and Cassidy.

silversonder requested spoiler tags on the achievement images, hence why they're there now.

You need to go on Date 11 with Iris in order to unlock a CG on the 2nd page of the gallery (3rd row, 4th column).

skysl∀shnova did some testing and found that you must go on at least Date 9 with Nyx and Iris in order to be locked to a certain romance route with the 60% Affection. I'm assuming this will also apply for all the routes in general. They also mentioned that certain events are locked to a specific timepoint, namely:

• Selene will always have finals in January and Chinese New Year happens in February.
  
  • This means that Date 6 for any of the love interests won't trigger outside of February.
• Nyx's November and December dates are fixed since she will be confined to the hospital in November-December and you need to see this happen in November in order to see the second half of the event in December. If you fail to visit Nyx in the hospital in November, she doesn't have an option in December.

MyLittleBingle pointed out that you only need the good endings for all 4 to unlock the true ending.

Hopefully, this guide helps anyone playing through the game! As always, doomed yuri is best yuri.

I'll try to keep this guide updated based on comments/feedback.
