Hi guys, I need your help identifying this manga (possibly a one-shot, old manga from the 2000s, and likely not very popular).

It’s about a high school girl (or student) who suffers from mental illness and suicidal thoughts due to guilt over her boyfriend's death on her birthday.

Her boyfriend died trying to retrieve an earring he had given her that fell into the middle of the road and got hit by a car. The girl always wears the remaining earring as a keepsake. (If I recall correctly, the earring is blue.)

Later, she meets a man and his niece, a young girl who survived a devastating earthquake. Both have their own stories of loss: the man lost his family in the earthquake, while his niece lost her parents but survived in her mother’s arms (his sister). Through their interactions, the girl slowly realizes that she is not the only one in the world suffering from loss.

One key scene: the girl receives a pair of earrings from the niece as a birthday present. They resemble the last gift from her boyfriend, triggering her unresolved trauma. She subconsciously gets angry and ends up hurting the niece’s feelings, causing the child to run away from home.
