Record of writing habits

Part 1: Can I Trust Myself?

01 You can't fly without staggering
02 Don't leave yourself alone
03 I hope you relax
04 Giving a big part of your heart
05 Run slowly and feel the wind
06 A mind that is strict only with itself
07 Chew on today's emotions tightly
08 Now only I move
09 What does wing size matter?
10 Adventures don't have to be taken for granted
11 You live only as yourself

If you feel alone even when you are together in Part 2

12 To a heart that does not even know its owner
13 The heart that learned before the word lonely
14 Why is the new skin visible?
15 Things that melt but do not disappear
16. The desire to be mean
17 Us of the past, Us of the present
18 So I turned seventeen.
19 small days gathered together
20 Colliding with Abyss
21 Leaning on the child's shoulder
22 Just silently, but very slowly
23 Someone who liked me before they even knew me
24 You are a very precious child

Part 3 When my love makes me anxious

25 I'm the only one who knows this beauty
26 Everything was shaking
27 Can we reach out?
28 I laughed along without realizing it
29 Because you are his only territory
30 Like a long-awaited welcome guest
31 Being the first
32 Why did you smile so brightly?
33 When there is something you cannot say
34 Being hated by someone you like
35 Keeping someone in mind
36 Come without knowing and leave clearly

Part 4 It's hard to find words to describe me

37 I hate introducing myself
38 Why do we not know the things of our hearts?
39 Finding yourself
40 The ground beneath my feet is very faintly floating
41 Maybe everyone is an alien
42 To be very ordinary or ordinary
43 So there is another secret in the world
44 My life, not the life the story dictates
45 Just say so first
46 Voices that give you the courage to hate to your heart's content
47 You must have had a hard time
48 Because there is no one without a shadow
49 I don't know, but still

Part 5: Can I Become the Person I Want to Be?

50 Wrong choices are not wrong
51 For whom and for what have I lived?
52 Something so desperate it brings tears to my eyes
53 Don't be swayed by what other people say
54 Meaning you can go anywhere
55 There is a law of flight
56 When I am lost and do not know where to go
57 Even though the outside looks the same, the inside is different
58 To stand in a high place
59 Come on, fly farther.
As much as you want

Part 6: When Courage is Needed to Create a Better World

60 More is better than one
61 Wounds are a prerequisite for new flesh to grow.
62 The beginning is to remove a single stone.
63 And yet it is not swallowed by the waves
64 I chose to move on rather than be sad.
65 Sheep that have escaped the fence
66 Staying together without running away
67 We live by overcoming
68 Because someday I will save someone else
69 It can shine more at the edge
To overcome the 70 limit

Sentences I want to remember for a long time
One line a day, sentences that protect me

Into the book
“You have to surrender to the wind, but sometimes you have to resist it. You can’t fly without shaking or swaying.
(…)
“Even if it’s scary, just watch over me.
“That’s our flight, Rain.”
--- p.20 From 『Gu Byeong-mo_Bird Strike』

“Don’t leave yourself alone.”
Those words really touched my heart.
As the conversation continued, I couldn't help but feel like I was talking to someone else besides Lee Do-hae.

“You are a meaningful person.”
--- p.22 From 『Kim Min-seo_Yul's Gaze』

Is there any expression of the heart as precise as crying? To cry for something, for someone, means to give a significant part of your heart.

--- p.26 From 『Cheon Seon-ran_Nine』

"Isn't it funny the more I think about it? Why are we so lenient with others, yet so strict with ourselves? We have to do everything well, be perfect, and yet we're never satisfied."
--- p.30 From 『Lee Hee-young_Nana』

The streets became quiet again.
I move in a town that has stopped.
Before, it seemed like I was the only one standing still, but now I'm the only one moving.
I can feel it.
I'm going to the competition.
I'm going step by step now.

--- p.34 From 『Kim Ryeo-ryeong_Wandeuk-i』

Adventure doesn't have to mean leaving the place where you were born and raised.
It is also an adventure to keep living in the place I have always lived in and to do things that others do not do.

--- p.38 From 『Kim Jung-mi's "I am Farmer Kim Gwang-su", _The Second Ending』

That's a truly lonely thing.
Having a heart that is different from anyone else's.

I learned that feeling before I learned the word lonely.
Now that I think about it, that's what it was.

--- p.46 From 『Lee Hyeon_The Story of Lake』

I began to dream, leaning on the shoulder of the child who once hated me the most in the world.
It was comfortable.
--- p.62 From 『Baek On-yu_Yuwon』

Publisher's Review
The beauty of sentences savored with your fingertips
A letter to the future, a consolation to the past


It is truly an age of desperation.
Following the rise of reading as a healing hobby that reduces stress, writing is also gaining attention as a hobby that expands vocabulary and thinking while recording one's own tastes.
In the age of images, videos, and artificial intelligence, what is the benefit of handwriting, of transcribing someone else's text?
The process of carefully writing carefully chosen words and sentences gives names to subtle emotions that are easily forgotten.
Even though I feel anxious because I feel like I'm struggling alone, when I read and write sentences that resonate with me, I find myself spending time taking care of myself, comforting and encouraging myself.


I slowly reflect on the strange and subtle emotions that have passed me by, transferring them to a notebook.
The sentences I choose contribute and influence my life in some way.
A letter to my future self and a comfort and encouragement to my past self.
_From Baek On-yu's "Time Dedicated to My Soul"

"One Line a Day, A Handbook to Protect Me" focuses on beautiful sentences that delicately examine emotions in various situations.
It contains sentences from youth literature that anyone, especially those suffering from growing pains, can relate to.
The carefully selected sentences from the Changbi Youth Literature series, which has long been greatly loved by readers, serve as a friendly guide for those who wish to become familiar with novels, and also provide deep emotions and profound inspiration to those who wish to experience the depth of literature.
When your wavering heart needs comfort and encouragement, lightly unfold the book and write down each sentence, one by one, and you will encounter the affection that literature conveys.


The joy of collecting your own sentences
A desperate time to focus entirely on myself


"One Line a Day, A Handwritten Note to Protect Myself" is a book that readers actively participate in and complete with their own individuality.
We have provided elements throughout to entertain readers who love records.
Since I don't know my own heart well, when I'm not sure what kind of comfort I need, I'll try the 'Heart Discovery Test' at the beginning of the book.
You will be able to find the sentences that are most necessary for you today.


After transcribing the sentences, I recommend that you write your own sentences using the 'Word of the Day' to reflect your feelings from that day.
This will be an exercise to strengthen the sentence structure needed for various types of writing.
If you fill in one box in your 'writing habit record' every day, you will be able to continue on an enjoyable journey like a challenge.
This book serves as a welcome gift, and with the hope that readers will encounter more books, it provides a page where they can collect their own sentences and record their reading.
I hope you enjoy decorating and filling the book in your own way, and building up your records.


When you feel overwhelmed by uncertainty about the future, anxiety about relationships, and loneliness, why not take a moment to focus on yourself, filling in the blanks one line a day?
You will be able to experience a moment of deeper understanding as you discover colors in your heart that you never knew existed.


Entering_From “Time Dedicated to My Soul”

When the world around me is noisy and my mind is in disarray, is it really a waste of time to seek refuge in type, to devote myself to drawing clean, clear strokes?
The time of devotion is the time devoted to the soul.
I slowly reflect on the strange and subtle emotions that have passed me by, transferring them to a notebook.
The sentences I choose contribute and influence my life in some way.
A letter to my future self and a comfort and encouragement to my past self.

I believe that I will gradually recover at the rate that the lead of a mechanical pencil wears out, and that after recovery, I will become stronger than before.
For this reason I also cover my delicate and fragile soul with a solid sentence.
