[Season 2 Chapter 1.
Development, Development, Climax, Conclusion]
It's already been 5 years since he and I started dating.
Meanwhile, Jeongguk oppa, who had been in the military, had to kneel for a year and a half, so he had to prepare for graduation with me.

A smile spread across my face as I saw him walking towards me from afar with long legs, wondering what was so enjoyable about him.
As soon as he saw me, he ran towards me on his long legs.
Then he locked me in his arms.
Perhaps because of the extremely cold weather, the tip of his nose was red, but I unconsciously closed my eyes as I was held in his warm embrace.

Yeah, so far so good.
But just like every story has a development, a climax, and an ending, about six months after he and I graduated from college and started living together, our relationship began to grow apart. In other words, it was a process of moving into a development phase?
He started waking up to a place called a club, where he met some friends, and he made a habit of coming in at the same time every day, around 4 AM.
I endured and endured this time that was always repeated.
Honestly, at first, I tried to understand. We'd just graduated and were under a lot of stress trying to find jobs, so I could overlook this. But as time went on, his behavior began to become increasingly out of line. Today, as always, at 4 a.m., I heard the door locking.
"Ji-eun~" Jungkook
He stumbles onto the bed, drunk and passed out. He used to be the type who couldn't even touch alcohol since we started dating, but these days, he drinks it like water. When I see him, I get angry and want to swear, but the moment I see Jungkook oppa's face, my anger disappears as if it never happened. I hate myself for being like that, I loathe it.

"Wash up and go to sleep"
I gently smoothed his hair and woke him up. Still, he remained silent. He wouldn't wake up, so I gave up and lay down next to him. "Good night," I whispered quietly into his ear.
I opened my eyes wide to the sound of my alarm going off every day at the same time. Then, seeing Jungkook oppa come out, drying his hair with a towel, I let out a guttural laugh.

"did you sleep well?"
"Yeah" Ji-eun said
"You fell asleep waiting for me again yesterday.. I told you not to wait for me.." Jungkook
His words made me choke up. But I didn't want to start the morning with a blush, so I raised the corners of my mouth and spoke as discreetly as possible.
"I'm waiting because I like you? Why? You don't like me?" Ji-eun

He frowned and looked at me, as if something had really hurt him. Then he abruptly looked away, grabbed a towel, and said nonchalantly, “I thought you might be tired,” before leaving for the living room. After he left, I sighed deeply. How long should I keep dating like this? I want to tell him not to go to the club. But every word I said to Jungkook oppa scared me. He was the first man I’d ever met in my life, and the man I’d known for five years, and I just didn’t have the courage to lose him over a single slip of the tongue and deal with the consequences.
[Chapter 2. In the end]
Today, as always, I was waiting for Jungkook oppa, but something felt strangely strong. Why? Then, a text message notification rang.
It was a text from my friend. I opened it with a chuckle, thinking it was my friend I hadn't heard from in a while, but there was a shitty video and a single line that said, "Isn't this Jeon Jungkook?" A cold sweat began to form on my back, and my body felt hot. With trembling hands, I clicked on the video, and it was a video of Jeon Jungkook passionately kissing a woman whose skirt was so long that it rode up just by walking. My mind was blank, and I ran to where Jeon Jungkook was.
The surrounding sounds were blocked out in my ears, and only the sound of my frantic heartbeat could be heard. I ran towards him, panting, but I saw a figure in the distance. A man and a woman were kissing, and Jeon Jungkook had one hand on her waist and the other on her leg. At that moment, I screamed "Hey!" like a crazy bitch, and Jeon Jungkook and the woman looked at me in surprise. Their faces were quite embarrassed and looked quite attractive.
I walked up to him and slapped him hard on the cheek. His head turned to the left, and I spoke in a trembling voice.
"How could you do that to me?" Ji-eun
"...." jungkook
When Jeon Jungkook glanced at the woman standing next to him, she ran away and when he turned his head towards me again, the confusion he had before disappeared and he looked down at me with unfocused eyes.
"I was wrong, so say something. Don't be a dick."
"..." jungkook
Everything came crashing down when Jeon Jungkook looked straight at me even though I was wrong. Oh, what have I been enduring for? It was me, with my head down and my eyes staring at the floor. Was it that bastard who was wrong, but I couldn't meet his eyes?

"You're getting angry now... isn't that funny?"
Those were the only words that came out of his mouth as he stared at me silently. His eyes were cold, not the ones I knew. Who would have thought I'd see someone change in an instant right before my eyes?
The happy times I had with him flashed through my mind.
"What did you say?" Ji-eun
"Oh my gosh, lol, that's funny. Even when we went to a club, he didn't say anything, but now he's saying this because he kissed a girl once" Jungkook
"Why are you suddenly like that, oppa... I told you not to do that!"
"You didn't? Right... You didn't. But people change, right?" Jungkook

"what..?"
What on earth happened that made Jeon Jungkook change?
No matter how much I thought about the past, I couldn't remember it.
[BEHIND]

Jungkook, who was sleeping quietly, was staring at Ji-eun with his arms crossed and a cold gaze. After staring at her for a while, he sighed deeply and went into the bathroom.
