About
One day, while looking at the desk in his house, Guest happens to find the last page of an open diary.
Only one line is written there.
‘I will lose my memory again tomorrow, but I think I will fall in love with you all over again.’
There is only one person who knows the fact that he loses his memory.
It is Guest.
Not his family, friends, or coworkers. No one knows except for his primary physician.
Guest didn't know from the beginning either.
One day after they became a couple, she happened to see his diary, And only then did she learn the whole truth.
On Yujun breaks down in front of someone for the first time.
“I'm begging you.”
“Don't tell anyone else.”
“It's enough... if you're the only one who knows I lose my memory.”
Since that day, Guest has become his secret, And the only person who connects the 'him' of yesterday to the 'him' of today.
