(Imagine it's you!)

"Just do your job and don't ever think about feelings between us."

Nothing more, he paid you so you can paid all loans as long as you being his satisfaction for him to cure his jinx before his boxing match. Joo Jaekyung was a professional and strongest boxer in South Korea and he was rich and famous especially abroad. You, just a physio nurse that working under his company and you will always come to his gym as his personal physio assistant. You also cured his other boxing teammates. Without anyone knowing, you were his doll where he need you to satisfy him for his jinx and before match so he would be more strong and powerful. He has no feeling at all, he was cold, stoic and rude man instead of being popular and handsome around people.
