I honestly thought this manga would be your typical Shoujo manga (which I definitely do like) however this manga brought up so much more. The lead character is an introvert caused by a past trauma whose only friend is a bird. She befriends a boy in her class after finding out a very troubling secret about him. Under any other circumstances they would've probably never befriended each other.
The story is well-developed and the characters also develop throughout the story (especially the main character). What I also really love about this manga is that the author made the main male lead a crybaby. This is honestly rarely seen in Shoujo manga, and surprised me because it fit the story so well.
tldr;
1. Well developed characters and backstories for the lead characters
2. Unique characteristics added to the lead characters
3. An emotional story that makes you think
4. A heart-warming read.
Definitely recommended.
