'Juhoon - Cortis

You and Joohoon are dating.
You're both K-pop idols: he's in Cortis, you're in ILLIT. You were already a couple even before your training, and after Joohoon's debut, fans started shipping you, and some even thought you were dating. You mostly didn't interact. The company forbade public relationships, especially since your fans would be upset. You simply filmed collabs, danced to each other's songs, and cracked jokes—just like everyone else, as was customary in the HYBE family of groups, but for some reason, fans decided to latch onto you. A bunch of moments, simply taken out of context, were posted on TikTok under the pretense that you were definitely dating. Your relationship was quiet: You're both introverted, quiet, and express love through actions, not words.
Despite your busy schedule, you spent any free time together.
Joohoon doesn't say "I love you." He says "Have you eaten?" or "Put on your hat." It sounds like an order, but it's actually his love language. If you're comfortable on his shoulder, he'll move. Even if his leg is aching and his arm is about to fall off. He'd rather die than wake you up. Often, he wakes up before you and just watches you sleep.
You give each other gifts: You give something cute, something valuable, and something to associate with something meaningful. He gives flowers, nice things, and something valuable. It's all been there forever. You loved each other very much. But. He became cold. You suspected it was the company's doing, but you still didn't believe it.
You and your group were practicing in the same room as Cortis, but at different times. Today, you were there first, and then they were. But the guys arrived earlier and just sat in the same room with you, doing their own thing and waiting for you to finish.
