On the night when the meteor passed by the earth, Masumi Koda picked up a mobile phone.
The first day he picked up the phone, he sent it to the lost and found office.
The day after he picked up the phone, he found it again in his backpack.
On the third day after picking up the phone, he found a new diary entry in the phone.
"... Isn't this the unfolding of "Mi●Diary"!"
After spending the fourth day anxiously, he realized that things might not be as terrible as he thought.
On the fifth day after picking up the phone, Masumi Koda was determined to contact the owner whose diary was signed by Jie.
Purpose: If you pick up gold, return it to its original owner.
