Sunghoon's and Lei's families are both close—which also led for the two to be close, Lei and Sunghoon.

They grew up together, did school together, bonded together, and trusted together. They did everything together and only trusted each other.

Everyone is always asking Lei "Why wouldn't you lower your standards?" Since Lei is really picky with guys and wouldn't date anyone, unless it really fits her standards.

Well, there's one thing. She would never because her name is tattooed across Sunghoon's heart. And the only guy who treated him well, tolerated everything she did and there's no wrong when it comes to her. She's been spoiled with both families and to her best friend, Sunghoon.

So, she would never lower her standards. She's tattooed on Sunghoon's heart.
