Lee Minho. The new unbeatable boxing champion of the world. He's very good.

But, he has a jinx. He has to have sex before every match or he'll do bad.

He didn't want that. So, he found someone who applied for the job as his physical therapist. Han Jisung. He needed money for his grandma's hospital bills.

Minho told him he'd have to take care of his jinx too.

Jisung wasn't gay. So he really wasn't sure about that. But, then again. It'd pay extra. So, he gave in. It's all for his grandma.

That's why he's here now, in Minho's apartment.
