Hi. These are my own notes that I made when reading through this VN,
and I figured instead of deleting it after reading this VN,
repurposing it into a reading log should be helpful for other people too.

The usual "choose everything related to the same girl and you'll be on her route" applies here.

However, there doesn't seem to be an option telling you the official titles of all the subchapters,
so I came up with some terms on my own, all of them being 5 words or less.

This should be able to help you keep track of:

• what did you read about.
  
• when did you read it.

TLDR, chronology stuff and how far into the route you are.

Personally, I'd recommend you read the story in this order.

First = Ai route
Some important Ai & Anzu information which will help you understand the subtle stuff in the other routes, and standard ending.

Second = Riko route
Because the annoying girl as the last route would be terrible indeed.

Third = Yurika route
Best route and apparently, True route

Too bad there's no Ren route or Sakuya route...

You'll run into this eventually.

CHOICE MODE
1) Coffee is good in the morning
2) but tea is nice

You can save / load to check out the differences,
its a few lines of immediate text at most, and doesn't seem to affect the endings.

Much later, you'll come across this screen.

This is where the storyline starts to diverge.

The SELECT A FLOWER screen is quite sensitive to your mouse cursor,
so just take a few seconds to hover on the girl you want to choose and get it right the first time.
(I've had a few times where I clicked too fast and got the wrong one)

TLDR; the girl's silhouette should go from 1/3 of the screen to 1/2 the screen, and after clicking, her full colored character sprite pops out.
