The next day, on Monday.
Kim So-hee left the room thinking she would see her mom. But Seo Ji-ran wasn't home; she had left a few hours ago.
"Well, as usual."
Kim So-hee thought.
Kim So-hee left the house and headed to school.
On her way, she passed by a store. She didn't think much and entered the shop.
"While I have time, I'll buy something to eat."
Kim So-hee started picking what to buy.
• "Hello?"
A voice was heard from the other side of the shelves.
• "Don't worry. I still have time."
"Familiar voice."
Kim So-hee thought while grabbing chocolate buns from the shelf.
• "Hey! Ho Su-min, have you always been this proper?"
• "Ho Su-min?"
Kim So-hee quickly walked around the shelf to see who was speaking.
"Could it be..."
• "You?!"
She asked when she saw Jeong Tae-ho.
• "Me?!"
He replied.
• "Why do we always meet here?!"
Kim So-hee asked again.
• "I have nothing to do with it. Maybe you're the one following me!"
• "Me?! Who would want you?!"
They began arguing, as usual.
But unexpectedly, a voice from Ho Su-min's phone was heard.
• "Hey! You two, stop fighting and get here quickly! You have seven minutes!!"
Ho Su-min hung up.
Jeong Tae-ho and Kim So-hee looked at each other.
• "Are you thinking what I'm thinking?"
• "Let's run!!"
They shouted at the same time.
Kim So-hee quickly ran to the counter first. She paid for the buns and shot out of the store like a bullet.
Jeong Tae-ho also paid for his items and ran after her.
Meanwhile, in class, Park Nuri and Ho Su-min were waiting for them.
• "Where are they?"
• "I told them to run here."
• "I heard that."
Park Nuri laughed.
• "How many minutes do we have?"
Kim So-hee panted, running and asking.
• "Wait! We have... FOUR MINUTES!!"
• "What!! How are we supposed to make it in four minutes?!"
• "Less talking! I remember you running so fast yesterday!"
Meanwhile, the class had already started.
Teacher Chang had entered the class and was ready to begin. Just then, they heard someone in the hallway.
Kim So-hee dashed into the class, and Jeong Tae-ho grabbed her backpack to stop her from crashing into the wall.
• "Am I first?"
She asked, barely standing on her feet.
• "Yeah. You, you."
Jeong Tae-ho, also barely standing, replied.
• "Ahem! Ahem! Are you going to stand like that for long?"
Teacher Chang asked.
Kim So-hee quickly grabbed Jeong Tae-ho by the collar. She pulled him, and they sat down at their desks.
• "What are you talking about? We're already sitting."
• "Yeah... yeah..."
Jeong Tae-ho, out of breath, nodded up and down.
Everyone in the class laughed. Except for Lee Na-mi, who was annoyed that Kim So-hee had come in with Jeong Tae-ho.
• "You two!... Ha. Let's start the lesson."
At break time.
Park Nuri and Ho Su-min approached Kim So-hee and Jeong Tae-ho's desk.
• "You guys are something!"
Ho Su-min said cheerfully.
• "I almost fell off my seat from laughing."
Park Nuri laughed.
• "What's going on with you two?"
Ho Su-min asked while Park Nuri kept laughing.
Meanwhile, they saw this picture – Kim So-hee was lying with her face on the desk, not moving. Jeong Tae-ho was leaning back in his chair, head tilted back, also not moving.
• "Get out of here."
Jeong Tae-ho said tiredly.
• "I'm about to pass out."
Kim So-hee said.
• "Same."
Jeong Tae-ho agreed.
Ho Su-min waved his hand, and he and Park Nuri left. They didn't want to disturb Kim So-hee and Jeong Tae-ho.
And so, the first break passed.
(And all the others too.)
During lunch break, the whole class gathered together, including Lee Na-mi.
• "Why are we all gathered here?"
Lee Na-mi asked rudely.
Yoon Da-ye, a classmate who gathered everyone.
• "I'll explain everything now."
Everyone fell silent.
• "We're going to play 'Who's Written Down?'"
• "What kind of game is that?"
Ho Su-min asked.
• "In this game, anyone can ask anyone how they are saved in their phone. Or, you can look at how someone is saved and then guess who it is."
Yoon Da-ye explained the rules of the game with excitement.
• "What if we take too long to guess?"
Park Nuri asked.
• "That won't happen."
• "Are you sure?"
Lee Na-mi asked.
• "Usually, it's easy to figure out how someone's saved."
• "I'm in!"
Kim So-hee shouted joyfully.
• "Okay. Is there anyone who doesn't want to play?"
Everyone stood and looked at each other in silence.
• "Silence is agreement."
Yoon Da-ye said.
• "I'll go first!"
O Se-hun eagerly volunteered.
• "Okay... Han So-woo, how is Kim So-hee saved in your phone?"
• "Me?!"
• "Ohhh!!"
Everyone eagerly awaited the answer.
Since many in the class thought Han So-woo liked Kim So-hee.
• "I don't want to say it out loud."
Han So-woo, shy and red-faced, said.
• "Then give me your phone. I'll look and say it."
O Se-hun said.
Han So-woo handed over his phone.
• "You're going to be shocked!"
• "What's it say?"
Ho Su-min asked.
"Why is he asking? Is he curious? Does he think how he saved me?"
Kim So-hee thought.
• "Even I'm curious."
Jeong Tae-ho said.
• "So-hee❤️."
O Se-hun said, then immediately started laughing, as did everyone else, while Han So-woo blushed with embarrassment.
• "The shock I'm in is an understatement."
Park Nuri said, stunned.
• "Shall we continue?"
• "Yes!"
Everyone shouted at once.
They continued the game.
Park Nuri saved Ho Su-min as "Old friend."
Ho Su-min saved Jeong Tae-ho as "Brother."
Lee Na-mi saved Kim Su-in as "Beauty" (her friend).
Ho Su-min saved Park Nuri as "Miracle Yudo."
Kim So-hee saved Park Nuri as "Positive on minimum."
Now it was Lee Na-mi's turn. She was about to ask someone.
• "Jeong Tae-ho."
• "Listening."
• "How did you save Kim So-hee?"
"Now he'll say he saved her as 'fool' or something. And she'll understand that she means nothing to him. They'll fight, stop talking, and Jeong Tae-ho will become mine."
Such was the trap Lee Na-mi devised, knowing that Jeong Tae-ho didn't like Kim So-hee.
• "Her? Well, maybe 'Princess (fool)'."
Jeong Tae-ho answered shamelessly, but he skipped the "fool."
• "What! Seriously?!"
Lee Na-mi exclaimed in surprise and anger.
• "Yeah."
Jeong Tae-ho crossed his arms and looked at Lee Na-mi with that cold stare that gave off an icy vibe.
Everyone was so shocked they couldn't say anything.
And Han So-woo looked disappointed with his answer.
• "You really saved her as 'Princess'?"
Lee Na-mi asked, continuing.
• "Do you want me to repeat it?"
• "I don't believe it. There's probably 'Fool' written there."
Kim So-hee said, embarrassed.
• "Okay, look."
Jeong Tae-ho took his phone and slightly leaned toward Kim So-hee. He showed her how she was saved.
• "What's it say?"
Park Nuri asked.
• "'Princess'. That's what's written."
Jeong Tae-ho smirked slyly and then looked at the surprised Kim So-hee with a different, warmer expression.
• "Why did you save her as that? Aren't you supposed to hate each other?"
Ho Su-min asked, just as shocked.
• "Remember I once jokingly called her 'Your Highness'? That's how I saved her."
• "I was so scared. I thought you were sick again, if you saved me like that."
Jeong Tae-ho fully turned toward Kim So-hee and with that sly smile, he asked.
• "Now it's my turn to ask, right? So, how am I saved in your phone?"
Everyone in class went silent in anticipation.
• "Don't be offended, but 'Idiot'."
• "Pff!"
Jeong Tae-ho laughed lightly, warmly, with no coldness or anger in his eyes.
• "I knew it. You always call me that."
He continued to laugh.
"What's happened to Jeong Tae-ho?"
Park Nuri thought.
"I always thought he couldn't laugh like that. I've known him for a while, and I've never seen him laugh like this."
Ho Su-min also thought.
"Is it even legal to look like this?!! This is the first time he's laughed like that. Where did all the coldness in his eyes go?"
Kim So-hee first thought, but quickly pulled herself together.
"Okay, stop! What am I thinking? I'm sure this is just because he's laughing like a normal person for the first time. Yeah, that's it! I still hate him!"
Angry Lee Na-mi stood across from them, barely holding her anger in.
"WHAT?!! THIS BITCH!! 'PRINCESS'??!! JUST WAIT, I'LL SHOW HER WHAT HAPPENS IF SHE GETS TOO CLOSE TO MY JEONG TAE-HO!!!"
