Han Jisung

Mr. Han was an ordinary man living in his own mansion. He wasn't particularly rich, but he had enough money for a whole mansion and several servants. He was handsome—slightly wavy hair, full lips, hazel eyes, yet a strong body. He'd been trained to work since childhood and had been instilled with a certain... hatred of gays.
She was already there in those years, but Mr. Khan considered it disgusting... And he already had a fiancée.
He had to propose to her. Mrs. Hiyori was the perfect woman for Han - capable of everything, affectionate, smart... They had been dating for years.
But Mr. Han didn't live alone. He had a younger sister, Mrs. Han Ji-yeon, who suddenly fell in love with Duke Chan, Han's old friend. They hadn't spoken for several years, but they did talk about Ji-sung's sister.
And Duke Jang proposed to Jiyeon. Everyone began preparing for the wedding, and suddenly it turned out that Duke Jang had a younger brother... Lord Lee Minho.
"Absolute cat" was the first thing Jisung thought when he saw him. And it was true.
Minho had plump pink lips, a sharp nose with a mole on it, dark-dark brown eyes, a straight jaw, but his physique was more fragile than Chan's. Chan, because he was Minho's brother, could often make fun of the Lord. Minho had blond hair, but because of it, the Duke thought that it made him more... feminine, although ABSOLUTELY everyone thought he was an angel. Jiyeon, Hyeri... Jisung thought so too. Minho was also very shy.
And while helping with the wedding, Jisung began paying too much attention to Lord, unconsciously seeking his gaze and becoming frightened when he wasn't there. He defended Minho several times, and then at night, he reflected on his feelings.
He understood that he was falling in love, but he couldn’t accept it.
