Part I: The Vent Maya starts the diary after a terrible week. Simon steals her design for a community center, and Elena ruins Maya’s rare Friday night off by bringing home a date who mocks Maya’s apartment. Maya writes her first entry. It’s petty. “I wish Elena would just choke on her own self-absorption. I hope Simon’s building falls down (without anyone in it, maybe).” It feels good. She sleeps better than she has in years. The diary becomes an addiction. Every time she swallows a rude comment or forces a smile, she rushes home to transcribe the ugly truth. She begins to feel lighter, sharper, and more confident. She thinks she has found a healthy outlet.
Part II: The Manifestation The "coincidences" begin. Maya writes: “I wish Simon would just slip and fall off his pedestal.” The next day, Simon misses a crucial meeting because he slipped in the gym and broke his ankle. Maya writes: “Elena doesn’t deserve that promotion. She’s lazy. I wish they’d see her for what she really is.” Two days later, an email leak exposes Elena’s time fraud at work, leading to her firing. Maya is unsettled. She tries to tell herself it’s just luck. But the power is intoxicating. For the first time, her life is running smoothly. Her obstacles are removing themselves.
Part III: The Escalation With Elena unemployed and depressed, she becomes clingy, leaning on Maya harder than ever. Maya feels trapped again. The "good girl" instinct wants to help, but the "diary brain" wants her gone. Simon returns to work early, bitter and vindictive. He targets Maya for a harsh performance review. Maya writes a new entry, fueled by wine and rage: “I hate them. I hate how they drain me. I wish they would just disappear. I wish they were gone forever.”
Part IV: The Twist The next morning, both Elena and Simon are missing. Police arrive at Maya’s work and home. They are asking questions. Maya is terrified—not just of the situation, but because she realizes she might be responsible. She rushes to burn the diary. But when she opens the book to tear out the pages, she finds new handwriting that isn't hers. The entries detail a physical attack on Simon and Elena. The handwriting is messy, erratic. Maya realizes she has been sleepwalking. Or rather, the diary has been writing itself through her. The "bad thoughts" weren't manifesting magically; they were commanding her subconscious body to act. She wasn't releasing the anger; she was training a attack dog inside her own mind.
Part V: The Climax The police close in. Maya finds evidence in her own closet—the "disappearance" was orchestrated by her own hands during a blackout state. She has trapped Elena in the basement storage unit and sabotaged Simon’s car. She is faced with a choice: Call the police and turn herself in, saving her friends but destroying her life... or write one final entry to "fix" it.
Epilogue: Maya sits in an interrogation room. She looks calm, polished—the "good girl" again. She tells the police she has no idea where Elena is. She claims she was home all night. The detective leaves, frustrated. Maya asks for a notepad to write down her statement. She clicks the pen. Her inner monologue is silent. She doesn't need the diary anymore. She is the diary now.

A surprising side effect of keeping this diary is improved communication. Most relationship fights happen because both partners are reading each other's minds and catastrohizing.
When you write down your "bad thinking" about your partner—"He is ignoring me because he doesn't love me anymore"—you realize the distortion is usually "Mind-reading." This allows you to approach them differently: "I had a bad thought that you are mad at me. Is that true, or are you just tired?"
We are often told to "think positive." We hang motivational posters, recite affirmations, and try to shove our doubts into a mental closet. But for millions of people dealing with anxiety, low self-esteem, or perfectionism, this forced optimism backfires. The more we try to suppress negative thoughts, the louder they scream.
Enter the Bad Thinking Diary.
At first glance, the name sounds counterintuitive. Why would anyone want to document their darkest, most irrational thoughts? Isn't that just wallowing in misery? Surprisingly, psychologists and cognitive behavioral therapists argue that a dedicated "Bad Thinking Diary" is one of the most effective tools for breaking the cycle of rumination. It is not a diary of self-pity; it is a diary of self-defense.
In this article, we will explore what a Bad Thinking Diary is, the science of why it works, how it differs from a standard gratitude journal, and a step-by-step guide to creating one that actually heals your mind.
A gratitude journal tells you to look at the light. A Bad Thinking Diary teaches you that the darkness is made of smoke. You need both.
You cannot be grateful if you think the world is ending. You have to clear the distortion first.
The Bad Thinking Diary is a map of the mind’s shortcuts, not a mirror of reality. If this diary were submitted to the board, the verdict would be: High emotional volatility, low evidence fidelity.
Final Recommendation: Do not throw the diary away. Instead, keep two columns. For every “bad” thought, force a “neutral evidence” counterpoint. The goal is not toxic positivity; the goal is accurate thinking. Accuracy is the only known antidote to a bad thinking diary.
Closing Thought: You are not your first thought. You are your second thought.

Bad Thinking Diary is a popular, high-quality GL webtoon by Hodan and Rangrari that focuses on the intensifying, dramatic relationship between college friends Min-ji and Yu-na. While praised for its art and erotic scenes, the series is often characterized by fans as a high-drama "guilty pleasure" due to its intense emotional conflicts and character dynamics. The series is officially available to read on Lezhin.
Bad Thinking Diary is a compelling South Korean manhwa that has captured the attention of readers worldwide. Created by the talented author and artist Hodot, this Girls’ Love (GL) series explores the thin, often blurry line between a lifelong friendship and an intense, overwhelming romantic attraction.
The story centers on Kim Min-ji and Kang Yu-na, two best friends who have been inseparable since childhood. Their relationship is built on a foundation of deep trust and shared history. However, as they transition into young adulthood, the nature of their bond begins to shift. What was once comfortable and platonic becomes charged with a new, confusing tension. This shift is catalyzed by a series of "bad thoughts" — intrusive, erotic, and emotionally heavy fantasies that Min-ji begins to have about Yu-na.
At its core, Bad Thinking Diary is a psychological exploration of desire. It dives deep into the anxiety that comes with realizing your feelings for a friend might be more than what is "socially acceptable" for your established dynamic. Min-ji’s internal struggle is the driving force of the narrative. She grapples with the guilt of viewing her best friend through a romantic lens and the fear that acting on these impulses could destroy the most important relationship in her life.

The manhwa is celebrated for its stunning art style. Hodot uses a soft, dreamlike palette that contrasts with the raw, often heavy emotional themes of the story. The character designs are expressive, effectively conveying the silent yearning and the moments of intense realization that the characters face. Every blush, lingering look, and hesitant touch is rendered with a precision that heightens the tension for the reader.
Furthermore, the series addresses the complexities of the "friends to lovers" trope. It explores the jealousy that arises when outside parties enter the frame and the possessiveness that can manifest when a platonic bond starts to change. It is a story about the messy, sometimes painful process of redefining one’s identity in relation to another person.
For fans of the GL genre, Bad Thinking Diary offers a detailed take on intimacy. It balances physical moments with emotional growth, ensuring that the connection between the characters is rooted in their evolving psychological states. It is a poignant reminder of how significant it can be to truly see someone known for a lifetime in a completely new light.

Create a new, rational statement that is not "toxic positivity" but simply true.
The term "Bad Thinking Diary" describes the unconscious practice of recording only the negative data of your life while filtering out the positive. It is the diary your Anxiety writes, not the one your Authentic Self writes.
Unlike a traditional journal that aims for accurate emotional reflection, a Bad Thinking Diary is biased. It thrives on exaggeration and catastrophe. It takes a minor mistake—sending an email with a typo—and enters it into the diary as definitive proof of incompetence.
