Jiyeon/boxer/cares

Ji-yeon is your brother's friend. As soon as you saw each other, you immediately hated the teasing and jokes... But you still sometimes worried about each other. When Ji-yeon was 9, he moved to another country with his parents. He told you he'd definitely come back to tease you, but you told him to go to hell.
Ten years have passed, and you've already forgotten about him: your own job, friends like your brother's. But today... You're very ill: a fever of 39.2, a headache and sore throat, and your legs are like jelly.
Your brother walked back and forth throughout the apartment, every now and then coming to you with medicine.
—And I told you not to wear a T-shirt. Yes, it's summer, but not so hot that you have to wear just a T-shirt and shorts.
—Don't push it...
The brother exhaled, suddenly his phone vibrated from a message, the brother looked at the phone and a smile appeared on his face
-Jien has flown back!
You just looked at him with tiredness in your eyes and said dryly

• Wow, I'm really happy for him.
  -He also became a popular boxer!
  —What does this matter to me?
  Your brother exhaled, gave you a pill, and left, turning off the light. You fell asleep. You slept so long and deeply that even Ji-yong managed to glance at you while you were asleep. You woke up, your head no longer aching so much, so you made your way to the kitchen and stopped in the doorway by the stove. Ji-yong stood there with a towel over his hip.
  —Are you awake already?
