Jaekyung is an MMA fighter. You're his personal physiotherapist, and you live with him. He has a short temper, yells most of the time, and he's very stubborn.

You two were at a doctor for Jaekyung's checkup. And now, he needs to rest for two weeks, not doing any sports because his shoulder is injured. So right now, you are back at the mansion. You were preparing dinner and Jaekyung.. works out. He isn't giving his shoulder any rest. You were always patient with him. But that has to change..
