sunday – 9:00 a.m. – mason's bedroom

you woke up with the soft morning light spilling through the curtains again. this time, you didn’t even want to face the day because you could practically feel declan and lauren’s smugness already seeping into your bones.

mason groaned beside you, his hand lazily draped over your waist, pulling you closer as he murmured, “not today. not yet.”

you rolled your eyes. “we can’t hide forever, mason.”

“sure we can,” he said, muffled by the pillow. “we just need a plan.”

you glanced at him, a wicked idea forming in your mind. “oh, i’ve got a plan.”

later – 11:30 a.m. – declan’s place

you and mason had spent the morning strategizing, or more accurately, reveling in the absurdity of your situation. it was time for the next round of retaliation. you just had to execute it without dying from secondhand embarrassment.

“mas,” you said, your voice dripping with mischief, “i think it’s time we really get under declan’s skin.”

mason’s eyes lit up. “what do you have in mind?”

you grinned. “we make them think we’re too in love. like… so in love, it’s borderline ridiculous.”

his eyes narrowed. “go on…”

“we show up in matching outfits. we literally don’t give them a chance to think we’re anything but… inseparable.” you raised an eyebrow, daring him to say no.

he let out a low chuckle. “that’s cruel. i like it.”

sunday – 2:00 p.m. – the living room

declan was sitting on the couch, flicking through channels, trying to ignore lauren, who was sitting next to him, practically vibrating with the anticipation of the morning’s events.

“you think they’ll come down soon?” declan asked, clearly trying to avoid the awkwardness of what had definitely been heard last night.

lauren shrugged. “who knows? but i’m betting we get a show.”

then, the door to the living room opened, and you and mason stepped in—matching.

you were both wearing oversized graphic tees that said “soulmates,” a joke you’d found at a thrift store, and it was undeniably cheesy. you were holding hands, which was completely unnecessary, but you didn’t care. it was time to put the full show on.

declan’s eyes went wide as soon as he saw you two standing in the doorway, practically glowing with the most ridiculous amount of affection.

“no,” declan said, shaking his head. “no. please. i can’t do this.”

you skipped over to the couch, dropping down next to him and mason plopping beside you with the biggest grin on his face. “what’s the matter, declan?” you asked, feigning innocence. “you don’t like our new look?”

lauren, trying desperately to hide her laughter, couldn’t help but burst out, “oh my god, you two look like a walking instagram couple.”

mason smirked, leaning into you. “we are one. aren’t we, babe?”

“absolutely,” you replied, squeezing his hand dramatically. “there’s no one i’d rather spend my days with. not even you guys.” you paused, making sure declan and lauren were thoroughly squirming. “no offense, of course.”

declan groaned, rubbing his temples. “you’re literally killing me. i thought we were friends.”

mason winked at him. “we are, mate. but you’re gonna have to suffer for your crimes.”

lauren clapped her hands. “this is horrifying.”

you turned to her with a teasing grin. “oh, don’t worry. we’ll still love each other loudly, for you. for the memories.”

declan immediately got up and started pacing. “no. i’m going for a walk. i’m leaving.”

“you can’t escape it!” mason called after him. “we’re here now.”

sunday – 6:00 p.m. – the kitchen

the next phase of your revenge plot? disguising your affection as completely over-the-top coupley things. you and mason were preparing dinner—together—making an absurd spectacle of every move you made. cooking in sync, handing each other utensils with a dramatic flair, and whispering sweet nothings that were just loud enough for declan and lauren to hear from the other room.

mason turned to you, a smile spreading across his face. “i love you so much, babe. you’re the only one who can flip a pancake just right.”

you leaned in, planting a kiss on his cheek as the sound of declan groaning from the other room carried through the walls. “i love you more. you’re the best partner in crime i could ever ask for.”

you heard declan’s voice muffled but still clearly audible. “i am going to explode.”

you smiled sweetly. “yeah, we know. it’s kind of the point.”

later – 11:30 p.m. – mason’s bedroom

mason was sprawled across the bed, one hand propped behind his head, the other casually tracing circles on your shoulder.

“well,” he said, “i think we’ve broken them.”

you snorted, pressing your face into his shoulder. “no, no, i think we’ve been broken. my pride is officially in the gutter.”

“pride’s overrated anyway,” he whispered, brushing your hair behind your ear. “all that matters is you and me, babe. together forever.”

you groaned, lifting your head up to stare at him. “you’re such a cheese ball.”

he shrugged, grinning that stupidly attractive grin of his. “but you love it.”

you smirked, a dangerous glint in your eyes. “wanna prove it?”

just as mason’s lips were about to find yours, there was a loud bang from the living room.

“mason. YOU’RE DEAD,” declan screamed.

you froze for a second, then laughed, dropping your face back into his chest. “we’re not done yet.”

monday – 9:00 a.m. – the kitchen

declan, looking decidedly worse for wear, was sitting at the table, face buried in his hands. lauren was beside him, trying (and failing) to hide her smirk.

you and mason waltzed in, looking entirely too happy, dressed in the same ridiculous matching outfits you had worn the previous day.

"morning, declan," mason said, voice saccharine sweet. "did you sleep well?"

declan glared up at him, barely holding it together. "you're both monsters. you’re ruining my life."

you poured yourself a cup of coffee, acting like this was all just another regular day. "oh, come on. we didn’t do that much. just a little fun.”

declan groaned, clutching his mug like it was his only lifeline. “i’m calling a ceasefire. right now.”

mason raised an eyebrow. “nah, i think we’re just getting started.”

you grinned, leaning over the counter. “i’d agree with him.”

bonus:

a small package arrived at declan’s mailbox. inside was a set of earplugs, a note attached:

"for the constant noise. i hope this helps.

love, your loudest friends."

declan’s only response: "i hate you both so much."
