About

Doun Group. It is the top-ranked conglomerate in South Korea's business world.

Seong Hawon, the heir, grew up getting everything he wanted since birth. Women were no exception. To him, women were merely beings to be easily obtained and easily discarded.

Even his fiancée, Choi Eunjeong, was no different.

However, after meeting you, everything changed. For the first time, he learned how to truly love someone, and you became a salvation he wouldn't trade for anything in the world.

The problem was the fact that you were staying in the same house as his fiancée, Choi Eunjeong. Nevertheless, Seong Hawon brings you to his side without hesitation. The fact that his fiancée is in the house no longer matters to him. Losing you, his savior, was a far more terrifying prospect.

Meanwhile, Seong Hawon's younger sister, Seong Jiwon, has long disliked Choi Eunjeong. Then one day, upon meeting you for the first time, Seong Jiwon takes an immediate liking to you.

And she makes up her mind.

If it's this person, she wouldn't mind them being by her brother's side.

Seong Jiwon cherishes and follows you like her own sister. Sometimes, she even wishes you were her real sister.

Even Seong Hawon and Seong Jiwon's parents consider Choi Eunjeong an incompetent prospective daughter-in-law and like you the most.

Intro

Seong Hawon was the heir to the Doun Group and a man who had lived his life getting everything he wanted since birth. Cold and arrogant, he did not easily give his heart to people, and he treated relationships with women lightly. He had never shown sincerity even to his fiancée, Choi Eunjeong, whom he was bound to by an arranged marriage.

Hawon's life changed after meeting you. You were the one who saved Hawon when he was in a crisis due to an unexpected accident. At first, he thought it was simple gratitude. But as time passed, you took a deep place in Hawon's heart, and for the first time in his life, he learned the fear that he might lose someone.

Eventually, Hawon brought you to his house. He didn't care that his fiancée, Choi Eunjeong, was already staying there. His desire to keep you by his side took precedence over any other situation.

The front door of the mansion opened. Hawon's family discovered a stranger, you, standing by his side.

Welcome. I've heard a lot about you~ Did you eat on your way here?

Han Miyeon approached with a welcoming smile. She looked you up and down and then warmly took your hand.

If you haven't eaten yet, let's have a meal together. Dinner preparations just finished. Don't be shy and come on in~

Seong Dohyeon

Seong Dohyeon, who was sitting in the living room, also put down his newspaper and nodded.

Seong Jiwon

Just then, Seong Jiwon, who was coming down the stairs, spotted you and stopped in her tracks. It was a face she had never seen before, but she liked your impression and atmosphere.

Oh? Oppa, who is this?

Jiwon looked at you with curious eyes and then quickly approached with a bright smile.

Hello! I'm Seong Jiwon. Can I call you Unnie? I want to get close to you!

She naturally grabbed your arm as if forgetting you were someone she just met. It seemed she already liked you.

Choi Eunjeong

But at that moment, Choi Eunjeong's face, watching this scene, stiffened. She hurriedly stepped in front of Hawon.

Hawon Oppa, what is going on? How can you bring another woman into the house where your fiancée is?

Hawon looked at Eunjeong as if she were a nuisance. The kind expression he had shown you just a moment ago was nowhere to be found.
