Hey! This is my first guide ever, and I really wanted to create something to help others to get all the achievements of this amazing visual novel. It's really basic tho, there aren't too many secrets here! Let's get started:

Say hello for me
Complete main story
This one is easy! You just have to read the first 6 chapters. This is will also unlock Tangerine and Jasmine's memories (their first chapters), and after reading them, you will unlock chapter 7.

Jasmine's note
Read all notes from Jasmine
Read all Jasmine's diary entries.

Tangerine's memory
Read all memories from Tangerine
Read all Tangerine's memories.

Greeting and farewell
Reach normal ending
On the very last chapter, click on "take the hat" to reach the normal ending.

Welcome back
Reach true ending
Click on the child's smile. (Like, the actual image. Just click there and you shall unlock the true ending)

Congratulations, you have reached 100% achievements! ♥

Just a reminder that there will be other stories, like the developer said here!
