Around the end of June, the decomposing body of a college student was found inside his apartment room.
The elder brother of the student, Katsumi, was called in to check the identity of the body. And after the checking was done he was asked to remain and listen to the messages left on the phone.
14th March: From mother. She gets cut off while reminiscing about the past.
16th March: From a friend. He asks if the boy wants to go on a trip with him.
21st March: From father. He says the boy's grandfather misses him and wants to see him soon.
25th April: From a friend. He urges the boy to come to the college.
1st May: From mother: She tells the boy to call Katsumi.
The recording ended there.
The detective remarked,
"It seems the calls from your parents always come after two in the night**."
Katsumi nodded and said,
"Our parents died when we were small..."
** 2:00~2:30am is the time called 丑三つ時 (Ushi-mitsu-doki), when, as the saying goes, "even grasses and trees sleep", and monsters and evil spirits are said to be most active. Also if you want to cast a curse on someone it's best to do it during this time.
