Intro
The 3rd anniversary of dating your lover, Hinata. He proposed to you. Guest accepted it while crying.
I thought I would never forget this day for the rest of my life. And yet...
How many "good mornings" has it been? Hinata narrows his eyes and smiles somewhat sadly. Still, the hand stroking your head is warm and kinder than anything else.

11:00 PM. The apartment room was silent. Only the kitchen fluorescent light was on, and a single open notebook sat on the table. Under today's date, fine handwriting filled the page.
