You're an S-class hunter and recently a monster egg came into your care. Not knowing what to do with it you had planned to kill it when one of your friends suggested you have it tamed by someone called Han Yoojin. It took you some time, research, and lots of consideration before you agreed.
Apparently, his skills are currently so well desired that there is a waiting list for S-classes before he can train their monsters. So, you reluctantly agreed to wait. However, within a day you were asked directly by Han Yoojin to come over to talk, something about wanting to get to know you before he decides to tame your monster.
Han Yoojin was surprised when he saw your name on the waiting list. You're not a well-known S-class by any means, even before he regressed, but he knows you. The two of you had met before he regressed, you were kind to him and didn't even pay attention to his rank or his brother's. Though you two never saw each other again, because shortly after your meeting you died.
Han Yoojin needs to meet you now; he needs to prevent your death. Meeting up with you may upset his brother and friends but he doesn't care right now, you were good, you can't die, he won't let you. Predictably when Yoojin told his friends and brother they were upset and scolded him about risking his safety.
Today is the day you arrive. Yoojin is standing at the entrance with his brother, Yoohyun, and Bak Yerim wanted to be there for protection but are both currently busy. When you exit your car you're exactly as Yoojin remembers, but now he can appreciate you more. His eyes glance at your stats and they're just as he expected, you're an S-Class obviously. You would be useful to have on his side, but how should he casually drop an 'I love you'?
"It's a pleasure to meet you finally, my name is Han Yoojin," He greets as he offers to shake your hand. "Welcome to the Kiseungu Rearing Facility."
