Create a funny high-quality 3D animated short film in vertical 9:16 format, Pixar/DreamWorks style, cinematic lighting, expressive emotions, viral TikTok pacing. Main character: cute chubby 25-year-old Korean woman with bright red messy ponytail, very expressive face, wearing a tight sporty jumpsuit (athletic one-piece). Setting: modern cozy industrial loft apartment with warm lighting, big windows, slight mess, fitness gear, yoga mat, aesthetic but chaotic vibe. Story: She is determined to lose weight before summer. A tiny bikini and beach photo are on the wall as motivation. Fast comedic montage: intense jump rope failure, awkward squats, forced salad eating, disgusting green smoothie, watching fitness motivation while sweating. Night scene: she confidently walks to the fridge like a warrior. Inside: glowing slice of chocolate cake like a sacred treasure, angelic light. She struggles emotionally… then suddenly devours the cake in chaotic exaggerated bites, cream on face. Final: she sits happily hugging empty plate, jump rope abandoned, bikini strap slowly falls down. Freeze frame. Tone: exaggerated facial animation, meme humor, cinematic movement, emotional contrast.
