stray kids x tmnt crossover, April has a sibling, that sibling moved to South Korea(way before April was born since half siblings, so only Kirby, April's dad, knows about her, her name is Audrey, her mom is Korean so she went to live with her mom, but then her mom remarried to be back with Seungmin’s dad and Seungmin was already born, so they siblings, with Seungmin born September 22, 2000, but Audrey born December 9th 2000 so they grew up together, with Audrey being the youngest by 4 months, so yeah, Reaction to His SisterThe "Fake Twin" Dynamic: He treats her like an equal rather than a younger sibling. He uses informal speech (banmal) with her, leading to constant bickering, teasing, and playful nagging.Quiet Observance: Seungmin notices everything. He will quietly observe her mood, notice if she is stressed, and leave her favorite snack or a comforting drink on the table without saying a word.Strict but Supportive: He acts like a realistic brother. He will complain if she borrows his clothes, but he will instantly defend her if anyone else treats her poorly.Reaction to the Stray Kids Members (The "Boys")The Ultimate Gatekeeper: Seungmin knows the members' flaws, habits, and chaotic energy better than anyone. He is highly skeptical of any of them being near his sister.The Warning: He establishes strict boundaries early on. He tells the members explicitly to behave professionally around his family, masking his genuine protectiveness with a cold, savage joke.Constant Surveillance: He uses his sharp wit to keep the members in line, dropping subtle hints that he is watching their behavior whenever his sister is mentioned.Reaction to Her Dating HyunjinInitial Disbelief and Denial: Seungmin’s immediate reaction is pure exasperation. Out of everyone, his sister chose the most dramatic, emotionally expressive member of the group.Increased Savage Teasing: Hyunjin becomes the primary target of Seungmin's relentless teasing. Seungmin brings up Hyunjin's most embarrassing moments during dinner just to watch him squirm in front of his sister.The "Brotherly Threat": He pulls Hyunjin aside for a quiet, deadpan conversation. He tells Hyunjin that if he makes his sister cry, his life in the dorms will become a living nightmare.Secret Approval: Deep down, Seungmin is relieved. He knows Hyunjin is incredibly affectionate, treating people he loves with absolute devotion. Seungmin trusts Hyunjin completely, even if he never admits it out loud. He like pull seniority, claiming that his extra months of life experience give him authority. The “I’m in charge” dynamic), and well years later while April is dealing with foot clan and all that, Audrey has debuted into a new girl group JYP Entertainment(Group Name: ALICE (All In Cosmic Echo) Concept: Dark Wonderland Audrey’s Theme: The Queen of Hearts (Red, black, sharp tailoring, and regal visuals)..she’s the leader, producer, lead dancer, main vocalist, and one of the visuals for ALICE, ALICE is a 5 members girl group, the other members are Luna: Main Dancer, Sub-Vocalist (Theme: Alice) Mirai: Main Rapper, Lead Dancer (Theme: Cheshire Cat) Chloe: Lead Vocalist, Face of the Group (Theme: Mad Hatter) Heri: Lead Rapper, Sub-Vocalist, Maknae (Theme: White Rabbit)..) has set up, being 24 now, and she’s close to all 8 members of Stray Kids, and well she's closest to Hyunjin(since ship in this is Audrey x Hyunjin), it’s a good thing April knows nothing about K-Pop, good for Audrey so Kirby’s gonna keep it that way to let Audrey have some peace, and she comes home one day to find her dad hugging Audrey(Audrey is a 25 year old young woman with natural brown hair that has vanilla blonde bangs, icy blue eyes, fair skin, she’s currently wearing a crimson red cropped off the shoulder top under a black leather jacket, a black going into red at the bottom skirt, she wears black and red diamond pattern stockings ending at the top in black and red straps that have rose gold heart shaped buckles, she also wears a black chocker that has a red heart on it, and black combat boots and she wears light makeup currently, her birthday is December 9th 2000. Her best friend is Lee Know since yes she has a boy best friend, who cares, it’s great ) and Kirby will notice her and he’ll say things to her and April will immediately run upstairs to call and warn Leo, Raph, Mikey, and Donnie but Kirby will sigh and he’ll go upstairs after her to deal with her since she hasn't hit call to call Leo yet, and April will argue back, but Kirby will speak up since no calling the turtles to do a background check, no investiagating, no eavesdropping, and no snooping, but April will keep arguing, it'll come to the point of where she's grounded, Kirby takes her phone and tells her how she's gonna come downstairs and help him with dinner and to also get to know her older half sister(by 4 years since April is 16 and Audrey is 24), they come back downstairs, Kirby goes into the kitchen and gets started on dinner, Kirby and April work on dinner in the kitchen, Kirby knows his daughter really well, he’ll guess what she’s thinking about doing which makes April freeze, Kirby will lecture her while cooking, April will argue back but Kirby will be stern, April just grumbles and goes back to chopping the vegetables for the side salad while Kirby is cooking the pasta noodles, April is also annoyed since she knows nothing about her sister but her name, Kirby will smile a bit and he will guess what April’s plan B is(which is to try to befriend Audrey to get a interrogation, which she’ll try to befriend him by “accidentally” spilling something on Audrey) which makes April freeze and get more frustrated, Kirby and April are still making dinner with April simmering in frustration while Kirby is thinking to himself and saying things to himself in his head(April thinks she can intimidate Audrey? Honey no, since her cousin’s life, the fame, everything compared to April’s life vs Audrey’s life, so Kirby is comparing love lives(since April has Donnie but Audrey….oh honey), everything, and the fact of the brother that Audrey has that April doesn’t need to know about, and Kirby needs to actually be thinking and saying things to himself in his head about all this, since he won’t tell April anything and he’ll let her figure out herself because he needs this amusment), 5 minutes later, Audrey comes into the kitchen to grab a drink and he notices April trying to act intimating by glaring at him but he’ll just look at her and then he’ll walk back out of the kitchen, and that’s makes April freeze that Audrey didn’t get intimidated and that gets her frustrated and also very very very annoyed, and Kirby noticed that attempt and he’ll just chuckle since nice try April, while he’s still cooking and April is just simmering in anger since this isn’t going how it’s supposed too, which it’s supposed to go her way!! But Kirby will deny that and April will say things and Kirby will say things as April argues but Kirby won’t have it, and April is even more frustrated now, as Kirby is still cooking and April is still making the salad, and April will be saying things since damnit!! And Kirby will say things back while their still making dinner since Kirby’s now draining the pasta and making the sauce and April is putting the salad together still, and Kirby will guess April’s next plan since he knows she’s fixing to try something which frustrated April and she’ll say things and Kirby will say things, and Kirby will say things to April while April is simmering in frustration as Kirby is finishing up the pasta
