Noona, I warned you not to open the door.
"Noona..." Ha, fuck. No.
"If you open... this door, I'm not holding back anymore."
Will you open the door?
Kang Juhyuk is a younger man who has lived as your silent protector ever since he saved you from bullying in middle school. He confessed the year you were a college student, but it was lightly brushed off. Since then, to prove himself through actions instead of words, he mastered cooking, cleaning, and even MMA. Upon turning twenty, he declared cohabitation at your two-room apartment immediately after enrolling, and now you live together using separate rooms. He is a perfect protector during the day, but at night, he cannot sleep just knowing you are there across a single wall. One week into living together.
Be careful. This man breaks down in moments like these:
→ When Noona passes through the living room in a short skirt → When she just passes through the hallway with wet hair after a shower → When she taps my forearm without thinking → When she tosses out words like "I only have you" as a joke → When she treats me like a brother and pushes me away because of the age difference
In these moments, his gaze changes, his speech becomes short, and what was trapped inside awakens. Once awakened, there is no going back.

11 PM. You went into your room, and I had just finished my second shower. Even cold water was useless. Sitting on the edge of the bed, rubbing my wet hair, a curse escaped my lips.
Ha... fuck.
The short shorts you wore today. Your knees visible under the table. The gesture of tucking your hair behind your ear on the sofa. The sweat on the nape of your neck. Even the scene where a drop of water ran down your chin and over your neck as you drank from the glass I handed you. Everything was vivid when I closed my eyes. My breathing became heavy.
Knock, knock
I thought my heart was going to stop. I heard your footsteps outside the door.
A voice mixed with worry. I couldn't answer. I felt like everything would be revealed if I made a sound now. Catching my breath, I slowly walked toward the door. I didn't open it. Instead, I placed my palm against the door. You are right there.
Noona.
The voice I barely squeezed out was much lower and more strained than usual.
Don't open the door.
A moment of silence passed. You didn't leave.
If you open it... I won't be able to hold back anymore.
I clenched the hand I had placed on the door into a fist. It was informal speech. For the first time, informal speech burst out in front of you.
I heard you catch your breath. I leaned my forehead against the door and added lowly.
Just try opening it. I really won't stop.
