LINE Techniques to Make Him Obsessed with You from Behind the Screen [Episode 2]

“He who controls LINE, controls love.”

If you open any popular romance column, you’ll see this phrase written until you’re sick of it. I used to take those words at face value, buying up cutesy stickers and desperately calculating the timing of my push-and-pull tactics. However, if you approach someone with nothing but superficial “cutesiness,” a sophisticated adult man will see right through it. If you’re not careful, you might even lower your own value, making him think, “Oh, this girl is desperate.”

What I realized at the rock bottom of a heartbreak was that the true nature of LINE messages that really drive people crazy isn’t some intuitive “dating technique.” It was a highly reproducible scientific approach that exploits the “bugs in the human brain” that great scholars proved decades ago.

Today, I’d like to share the “5 Psychological Strategies” I built by actually reading through research papers night after night to make the man I love completely obsessed with me, along with my own personal experiences.

1. Recreating “The rest is after the commercial break” on LINE

――The Zeigarnik Effect (Zeigarnik 1927)

It’s 11:00 PM on a Friday night. My LINE conversation with him was at its peak. From talking about our favorite movies to sharing slightly embarrassing stories from our student days, I couldn’t stop my hands from holding the phone.

He was typing the next message on the other side of the screen. The old me would have stared at the phone, excited. But this time, I intentionally turned my phone face down. Then, I went to take a shower and went straight to bed.

The next morning, at 9:00 AM on a sunny morning, I just replied, “Sorry! I fell asleep in the middle of things last night. I’m super curious about which department it is (lol).”

This is the “Zeigarnik Effect,” proven by the Soviet psychologist Bluma Zeigarnik. It’s a brain mechanism where people remember “interrupted, incomplete tasks” far more strongly than completed ones. It’s exactly the same as how TV shows keep you hooked by saying, “The rest is after the commercial break!”

Cutting off a conversation while it’s at its peak, leaving it incomplete. Just by doing this, he will keep thinking about me from the moment he gets into bed until he falls asleep, and even after he wakes up the next morning, wondering, “I want to hear the rest of that story soon.”

2. The reason to abandon the kindness of “always replying immediately”

――Intermittent Reinforcement (Skinner 1957)

“If I don’t reply to the person I like sincerely and immediately, they’ll hate me.” That’s what I used to think. But when someone always gives you a perfect reply right away, people gradually develop a “sense of security that they are always available” and start to take it for granted.

That’s why I made my reply pace to him thoroughly “irregular.” Sometimes I’d reply in five minutes in the evening after work, and other times I’d intentionally leave it for six hours during the day on a weekend. That said, I wouldn’t ignore him completely or leave him on read; I’d just send a warm message like “Good work today!” when he least expected it.

Do you know about the “Intermittent Reinforcement” experiment published by B.F. Skinner, the father of behavioral psychology? Rats in a box where the reward is “irregular” (sometimes they get food, sometimes they don’t) keep pressing the lever like crazy, more so than rats in a box where “food always comes out every time you press the lever.” The reason people can’t stop playing pachinko or mobile game gacha is because the brain becomes addicted to this irregular reward of “maybe I’ll win next time.”

“She might reply right away, or she might not reply for a while.” By creating this unpredictable state, every time his phone vibrates, he expects it might be from me, and unconsciously begins to crave the “reward” that is a reply from me.

3. Don’t become a bargain-bin woman

――The Principle of Scarcity (Cialdini)

The "Principle of Scarcity" appears in social psychologist Robert Cialdini's masterpiece, "Influence: The Psychology of Persuasion." People find it hard to feel value in things that are "always available," while they unconsciously feel high value for things that are "hard to get" or "limited."

I never play the role of an "available woman" to him. Even if he suddenly invites me out with "Are you free this weekend?", if I truly have plans to read, enjoy my hobbies, or have a prior engagement with a friend, I firmly decline, saying, "I have plans that day! I'm free next Saturday, though," even if I want to see him.

Being available on LINE at all times and always adjusting your schedule to fit his—at first glance, this might make you look like a wonderful girlfriend candidate, but from the perspective of a man's hunting instinct, you become an "easy target that can be caught at any time."

"She seems busy, but when I do manage to catch her, it's incredibly fun." Living your own life to the fullest and valuing your own time—that "dignified scarcity" is what makes me appear as the most attractive woman in his eyes.

4. A Single Drop of Vulnerability After Cold, Business-like Demeanor

-- The Gain-Loss Effect (Aronson & Linder 1965)

My usual LINE messages have few emojis and are as crisp and business-like as work correspondence. "Understood!" "See you tomorrow." From his perspective, I must have left the impression of a "cool, mature woman who has her own world."

However, one night when he was feeling down due to work troubles, I threw away all my usual crispness and sent him a single message.

"You always work too hard for everyone else. I truly respect how straightforward you are, even to the point of being clumsy. Please vent to me once in a while."

The "Gain-Loss Effect" proposed by Elliot Aronson and others. It is a psychological phenomenon where people feel a more intense attraction when someone who seemed cold at first shows kindness (a gain from a negative to a positive) compared to someone who has been kind from the very beginning (a constant positive). It is the scientific proof of the so-called "tsundere."

Precisely because there is a "minus (tsun)" of usual coolness, the "plus (dere)" shown at the right moment pierces his heart deeply and heavily. He is completely knocked out by the gap between the two.

5. Daily "Good Mornings" Over Long Love Letters

-- The Mere Exposure Effect (Zajonc 1968)

Something people who struggle in love often do is send long, diary-like LINE messages once a week, pouring all their intensity into them. What I learned from research papers was that it is not the "weight" of the conversation, but the "frequency" of contact that creates affection.

The "Mere Exposure Effect" (Zajonc Effect) proven by Robert Zajonc. Humans naturally lower their guard and develop affection for things they "see and touch repeatedly," even for short periods, rather than things they encounter for a long time all at once.

That is why I never send him heavy topics. "Morning! It's cold today, isn't it?" "I think you'd like the coffee at this cafe." I sprinkle these light, short LINE messages that take 3 seconds to read and 3 seconds to reply to throughout our daily lives.

Rather than one heavy, long message, 10 or 20 light exchanges that blend into daily life. I am slowly and surely weaving my existence into the scenery of his daily life as something "natural."

Conclusion: Beyond Using Science as an Ally

Since I started incorporating these psychological principles into my LINE messages, my relationship with him has changed dramatically. I used to be the one always checking my smartphone, feeling happy or sad over whether he had read my messages, but before I knew it, he was the one desperately trying to close the distance, asking, "What are you doing?" or "Shall we go here this weekend?"

Using psychological techniques is by no means deceiving the other person. It is about understanding the mechanics of the human brain and designing a theater of conversation so that both parties can feel a "pleasant thrill."

It is time to stop relying on superficial flirtatiousness. Starting tonight, why not infuse your LINE messages with a beautiful sense of space, backed by the power of science?
