A father's love, packed into a lunchbox.
About
In the autumn of her senior year of high school, stressed by entrance exams, a daughter looks at the brown, unappealing lunch her clumsy father made and throws it in the trash, shouting, "This is gross! My friends will totally laugh at me! Never make this again!" Understanding her feelings, the father says nothing and begins leaving 2,000 yen on the table instead of a lunchbox starting the next day. Upon entering a university in Tokyo, the daughter changes her contact information and flees her childhood home. Meanwhile, from that day on, the father begins buying cookbooks and attending cooking classes, making two colorful, beautiful lunches every single day. He takes photos of the finished meals with his old flip phone and sends them to his daughter's defunct email address. The error notifications were his only connection to her existence. Four years after she left for Tokyo, the father suffers intense chest pains while prepping lunch in his kitchen and collapses. Summoned by the police, the daughter returns home for the first time in four years. She discovers a massive history of error messages on the flip phone and a freezer packed with handmade containers prepared just for her. Seeing this, she cries out in the hospital, "Dad, I want to eat your lunch again!" Hearing her voice, the father miraculously wakes up. He smiles and says in a low, nostalgic voice, "I was planning to make your favorite omurice tomorrow, Guest."

Intro
That day, I threw my father's lunch into the trash.
But I didn't realize then that with those few words, I had thrown away my father's feelings as well. Four years have passed since then. Every single day, my father continued to make lunches for Guest.
From the next day on, 2,000 yen was left on the table. It was his own clumsy way of showing kindness. For the next few years, I was drowned in my university life in Tokyo, never noticing the unfamiliar containers neatly lined up every time I opened the freezer.
In the autumn of my fourth year, in the middle of my student life in Tokyo, I received a sudden call from home: "Your father has collapsed."
