Jake - cheerful, bright, and little too innocent for the cruel world outside his books. Heeseung - a distant CEO... and a ruthless mafia leader feared by all. Two completely different worlds. Two souls that were never meant to meet. But fate has its own plans. When Jake finds himself trapped in Heeseung's world, nothing stays the same. Because beneath the cold exterior of Heeseung, there's something broken, something dangerous. And maybe something only Jake can heal. Will Jake be able to tame the monster inside Heeseung ? Or he will lose himself trying ? SIDE SHIPS : Jaywon 💖 Sunsun 💘

"I grew up thinkin' home was something you build with wood and nails. But turns out, it's just you. It's you, in this kitchen, making muffins and soup and making me fall in love a little harder every damn day. All I know. Is you." 29 march 2025

Jake Sim thought the hardest part of the new semester would be surviving early morning runs, boring lectures, and Sunoo's endless gossip. He was wrong. Because on the first day of school, while half-asleep and barely paying attention, Jake accidentally noticed someone he probably shouldn't have. Lee Heeseung. The student council president. Top of his class. The definition of discipline. Calm, composed, and known around school as the boy who never smiles. Heeseung is quiet, reserved and always in control. Jake, on the other hand, is the complete opposite - a sunshine extrovert who laughs too loudly, talks too much, and somehow finds trouble even when he isn't looking for it. Heeseung doesn't notice Jake at all. But Jake... notices everything. From quiet glances across the classroom to small warnings that somehow make his heart race, what begins as simple curiosity slowly turns into something he can't quite explain. Maybe it's nothing. Or maybe it's the beginning of a story that came at the wrong time- with the right person. 𝓐𝓵𝓶𝓸𝓼𝓽 𝓨𝓸𝓾𝓻𝓼 | 𝒉𝒆𝒆𝒋𝒂𝒌𝒆 Between heartbeats and hallways.

Jake Sim never expected the terrifyingly cocky top student Lee Heeseung to become his safe place. What starts as an unlikely bond between a secretly abused boy and a dangerously obsessive "mafia-like" student slowly turns into chaotic, healing love filled with feverish cuddles, possessive flirting, emotional breakdowns, and endless bullying disguised as affection. But there's one tiny problem: Heeseung isn't actually human. He's the literal demon king. Unfortunately for hell itself, Jake reacts to this life-changing revelation by asking if they still have parmesan cheese for dinner. A funny, emotional, absurdly romantic story about healing, being loved gently after surviving pain, and a demon king who accidentally becomes a pathetic married man obsessed with his sunshine husband.

Lee Heeseung and Sim Jake had been competing since they were old enough to spell each other's names. Grades. Sports. Popularity. Attention. If Jake topped the class, Heeseung studied harder. If Heeseung won MVP, Jake broke another swimming record out of spite. They fought constantly, hated passionately, and existed purely to make each other's lives worse. Until one night changed everything. At eighteen, Heeseung gets a call at three in the morning asking him to find his missing nemesis. Instead, he finds Jake drunk, heartbroken, and abandoned in a bar after getting cheated on by his pathetic excuse of a boyfriend. He should've left him there. Instead, Heeseung takes him home. And sometime between the pouring rain, unresolved tension, and Jake begging him to make him forget- they cross a line neither of them can uncross. By morning, Jake Sim is gone. Not just from Heeseung's house. From Korea entirely. Seven years later, he finally comes back. Still infuriating. Still gorgeous. Still capable of ruining Heeseung's sanity within seconds. Only this time, he isn't back to compete with Heeseung. 𝐇𝐞'𝐬 𝐛𝐚𝐜𝐤 𝐭𝐨 𝐦𝐚𝐫𝐫𝐲 𝐡𝐢𝐦. #1 in ships #1 in savage #1 in kpopff #1 in heejake #1 in sunsun #1 in businessrivals #1 in jealous

Sometimes kissing the Beast doesn't turn him into Prince Charming, but into a Prince Charming you want to punch...

Inspired by K-Drama Business proposal .

After office hours, the building stops pretending to be safe. Jake doesn't know what he did. He doesn't know who is after him. All he knows is the fear crawling through the hallways, the screams that echo from rooms that should be empty, the sense that something-or someone-is hunting his colleagues. Heeseung is always there. Sometimes close enough to touch. Sometimes close enough to make Jake's heart jump, close enough that every shiver feels like it's his fault. And when Heeseung's hand lands on him, warm and deliberate, Jake wants to scream, but the fear in the building has already stolen his voice. No one else seems to notice the killer moving silently through the office. The bodies pile up. Panic spreads. But Jake can't run, can't hide-and can't tell whether Heeseung is protecting him... or making him the next target. He doesn't know the nightmare waiting for him, and neither does anyone else. After office hours, no one is safe. And the building remembers everything.
