Write a very long, elaborate, descriptive and detailed shooting script, including a background and dialogues, for a K-Drama comic scene according to the following scenario: Two female flatmates are stuck in the car during a traffic jam (give them names, and describe their in detail appearance and clothing in detail; the passenger is wearing dress trousers and the driver is wearing leather bermuda shorts). The passenger asked the driver to pick her up from work because she has to move her bowels urgently, but she didn't want the driver to know this and gave some other reason when she asked the driver to pick her up. Before this point, they haven't been living together for long and are still in the stages of getting acquainted. Hence, they aren't very close yet. They have contrasting personalities - the passenger is introverted and reserved, the driver is quirky. As they sit in the car, the passenger doesn't want the driver to know that she needs to use the restroom. She had been holding her poop back all day at work because she is too embarrassed to poop outside of her home. She usually poops in the morning, but overslept that day and missed her opportunity to have her morning poop at home. She is desperately resisting the urge to poop while they are stuck there in traffic and doesn't want the driver to notice or know that she has to use the restroom. The pressure builds and builds. She manages to resist for a while, but gradually loses control, until she finally can't take it anymore, releases voluntarily to alleviate the immense pressure and fills her trousers with a hefty load right there in the car (describe this in meticulous detail). She is mortified and keeps quiet because of this. After a few moments, though she can't see the passenger's rear end, the driver realizes what happened and is deterred by the stench. This causes the passenger to feel even more embarrassed. The driver then regrets her initial reaction, but is taken aback by the passenger's accident and thus is unsure how to act. The passenger, for her part, is still distraught. There is a momentary awkward silence. Once the conversation grows silent again, the driver gets an idea. Following a momentary dilemma and contemplation, and though she is hesitant to follow through, she decides to poop her leather bermuda shorts too so she can cheer the passenger up by sharing her plight (describe this with a character voiceover). She had an urge to move her bowels as well, a regular and not an overbearing urge, which she too had kept to herself up until that point since she wasn't as desperate as the passenger. She carefully raises a bum cheek off of the carseat, begins to push discreetly, and tries to suppress her facial expressions and grunts so the passenger won’t notice what she is doing. Though it takes her a little while, she finishes relieving herself in her leather bermuda shorts too (describe this in meticulous detail). She could feel the poop coiling and piling in her pants (describe this in detail). She is surprised of herself, of the occurrence and of the sensation as this is happening, but is feeling relieved at the same time (describe this in detail). After she finishes, she hesitantly sits back down her slightly raised bumcheek on the carseat (describe this in detail). She tries to hide her expression of relief from the passenger. Initially, the passenger doesn't understand what just happened. She can't notice what the driver did through detection by smell, because a stench already lingers in the car from her own accident. Therefore, she becomes aware to the driver's predicament only once the driver suggestively and teasingly leads her to realization through insinuation (elaborate on this dialogue). It takes the passenger a few moments to understand what the driver has done. Once she realizes that the driver pooped her pants too, it slightly cheers her up. They begin to teasingly joke about what had happened, about the stench in the car, and about how the poop feels inside their pants (elaborate on this dialogue).
