How each group member would react:

If he accidentally walked in on you undressing to take a shower.

---------------------------------------

Jungkook: you had decided to take a shower as your boyfriend Jungkook watches his favorite TV show. You drop your hair from your pony tail, just then the door swings open. And its none other than Jungkook himself. His eyes widen and he turns around. "I'm sorry Jagi.." He says shyly as if he hasn't seen you naked before.. But to be honest.. You weren't fully naked at all, just your shirt was off. You chuckle at his innocence. "Its okay Kookie." You tell him as you walk up to him. And hug him from behind. He was surprised at first by your action, but the familiar sensations ran through his body making him comfortable. He turns and kisses your forehead. "I'll let you take your shower now." He smiles. You nod and he walks back to the living room.

Taehyung: You grab your clothes and make your way to the bathroom. Down the hall you realize that its much too quiet in the apartment. You started to grow suspicious of Taehyungs where abouts, he was never this quiet. He was always up to mischief. You walk into the bathroom and start the water. Dropping your clothes on the sink and hanging your towel. You hummed to your favorite song as you undresses. You were about to clip your bra when the door bangs open and there's Taehyung himself. "Y/N!!!" He screamed. You jump in surprise. "Yah! Tae!" You grab your towel and cover yourself. He smirks and his eyebrows go up. "I caught you at a great time." He walks towards you. Your face heats up to his words, as you walk back there's no where else to go when your back hits the shower door. His hands pulling on the towel, you let it fall to your feet. He smiles at the sight of you letting him do as he pleased. He leaned in and unbuckled the back of your bra. Your stomach twisted and knotted to his actions. His eyes stare at your bra as if slowly fell off, his eyes not daring to leave your unclothed breast. "Now you help me undress?" He asks smirking.

Hoseok: you finally undress and check the temperature of the water with your hand. It was still much too cold. Your about to bend over to change the temperature when the door opens. You drop to the floor and cover yourself, you find yourself relieved when its just Hoseok.. Who else would it be? "Oh! I'm so sorry y/n.. Get back to your shower preparations." He nods and closes the door.

Yoongi: The water felt great on your dry skin, your eyes closed and a small smile spread on your face. It was captivating and soothing. Everything about the steam and cleanliness made you happy. Just then you hear the door creak open. Your eyes shoot open and you wipe your hand on the glass of the door, cleaning the fog. Its Yoongi, and he shoots you a smile. "May I join? We can save water." Your heart stops. Without invitation or an answer he let's himself into the shower and right up against you. His lips right away locking with yours. "Let's just pretend that you dropped the soap." He smirks turning you around and bending you over.

Seokjin: you mentally scold yourself for forgetting your towel. "Seokjin!" You call. You grab your shirt and try to cover as much of yourself as you can. "Yes!?" He answers. "I need a towel!" You yell over the running water. There's a knock on the door and you open it for him. His face looked the other way as he handed you the towel. You smile at how respectful he is. "Thank you." You tell him before grabbing his face and kissig his cheek. A smile spreads upon his face and he nods, not once glancing at your naked body but into your eyes.

Jimin: You walk into the bathroom, to only have him walk up behind you. You turn. "No Jimin." You point at him. He bites the tip of your finger. "Yes y/n." He pushes you into the bathroom. You chuckle. "You're so stupid sometimes." You kiss his thick lips that were only for you. His hands roaming your body and slowly pulling on your clothes.

Namjoon: you lay out your clothes on the toilet and begin to undress. "Y/n?" The door opens. His eyes widen. "I'm so sorry." He gasps and covers his eyes and stands there. "What did you need?" You ask. "Where's the blender?" He asks. You laugh. "Connected to the wall." You say. You can sense him smile. "I know... I was just hoping you'd be undressed when I walked in." He removed his hand and threw you his signature dimpled smile. Your jaw dropped to his unexpected goal. "You look good by the way." He says checking you out before turning and leaving the bathroom. You were left confused and dumbfounded.
