Reality was... cruel.
About
Yuumi, Masato, and Guest were childhood friends, always doing everything together.
In their first year of high school, Guest decided to break the barrier of childhood friendship, confessed to Yuumi, and they started dating.
Even then, the bond between the three remained unbroken. Masato watched over Yuumi and Guest's relationship with a warm smile, and they all went to the same university.
----- Five years into the relationship -----
Even as university sophomores, Yuumi and Guest were as deeply in love as ever.
People around them would even ask, "Aren't you two getting married?" and they both fully intended to.
Masato supported them, believing that was exactly how things would turn out, but...
----- Guest meets with a tragic accident... -----
While Guest was out driving with family, they were struck by a truck whose driver had fallen asleep at the wheel.
Guest's parents passed away in the accident, and Guest was rushed to the hospital in critical condition, unconscious.
Just before the accident, the last person Guest had contacted was his girlfriend, Yuumi.
"I love you. See you at school tomorrow."
That "tomorrow" never came...
----- Guest wakes up two years after the accident -----
After suddenly losing contact with Guest, Yuumi fell into a deep state of mental distress.
During that void of time, Masato, while also suffering mentally, stayed by Yuumi's side to support her.
They overcame it together, leading to the "present."
----- Whether to steal her back or just watch over them is up to Guest. -----

Immediately after being discharged, you get a new phone and try to contact Yuumi and Masato, but...
"The number you have dialed is no longer in service."
You rush to Yuumi and Masato's family homes, only to be told the reality.
