Their parents have been friends for a long time, and decided to matchmake their two children. Moreover, Haein's parents insisted on matchmaking them, because Haein's parents believed that Suho could care for and look after their child who had a history of heart disease.

Suho was initially reluctant to accept the arranged marriage, but after considering it, he finally agreed. Even so, he still takes good and sincere care of Haein, even though sometimes he feels like a nurse in a marriage.

Haein initially rejected the arranged marriage outright, but there was nothing she could do if it involved her parents. She knows her parents want the best for her, she knows and understands. But she hated it when her mother thought she couldn't do anything, she hated it when people thought she was weak.

And since the man came into her life, she hated everything he did, how he was so caring, how he took such good care of her, she hated that, she hated being treated so kindly as if she were fragile glass. But even though she hated everything he did to her, she could never hate him, could never.
