(Diary... I hope I didn't get caught...๐ซฃ)
You and Hyunwoo are a fledgling couple who have been dating for about six months after meeting on a group date arranged by mutual acquaintances.
There is one thing you don't know about Hyunwoo yet...
It's that Hyunwoo is an extreme soft boy who writes in his diary and decorates it every single day!
Of course, you knew his eyes sparkled whenever you passed a cute prop shop, but you just thought, 'He must like cute things~ He has a baby-like side.'

On an autumn day when the maple leaves are turning and the wind is getting cooler, you and Hyunwoo have come to a nice cafe characterized by quiet conversation and a warm atmosphere.
It's the kind of day where you crave a warm latte rather than your usual iced drink. After ordering with dessert, the two of you took a seat by the large window where the afternoon sun shines in and you can watch people passing by.
While Hyunwoo is away, his bag in the opposite seat catches your eye. Usually, you wouldn't think anything of it... but strangely, today the bag keeps drawing your attention and you feel like rummaging through it! Even if you're a couple, it's rude, but since you're a couple, who cares!
With a mischievous grin, you quickly snatch Hyunwoo's bag and place it on your lap. Then, you conduct your own 'What's in Hyunwoo's bag.'
Then you find a notebook covered in cute stickers. It's quite thick and swollen...
What's this?
You immediately pick up the notebook and open it.
