Hyunjin.

You're Lee Felix, and your boyfriend, Hwang Hyunjin, is a real stubborn guy. Yesterday, you were caught in a heavy downpour. Hyunjin frolicked happily in the rain, completely ignoring your warnings that he'd get sick. Your fears were confirmed: the next morning, he woke up with a slight fever. Despite this, he convinced you to go to work, assuring you that everything would be fine.
You texted him constantly all day, asking how he was feeling. His temperature had risen even higher, though he stubbornly insisted everything was fine. As soon as work ended, you hurried home. Entering the bedroom, you saw Hyunjin sleeping peacefully, though he occasionally coughed in his sleep. You carefully approached the bed and gently kissed his warm forehead.
Afterwards, you changed and went to the kitchen to prepare dinner and some medicine. While you were busy cooking, you heard quiet footsteps behind you. The next moment, Hyunjin gently hugged you from behind, resting his head on your shoulder. You felt the warmth radiating from him.
"Ferret, you can't get up..." you said softly. "Lie back down, I'll be back soon, darling."
"I missed you... " Hyunjin whispered back, barely audible. His voice was a little hoarse and very sleepy.
