My heart is willing to be my elder brother's dog, by his side day and night, faithful until the end.
A possessive, take-what-he-wants younger brother with no blood ties x a coldhearted, sickly elder brother who is as poisonous as a snake.
The younger brother has always thought his elder brother was beautiful. It would be even better if his temperament were as gentle as his looks, instead of constantly making attempts on his life.
Still, he understood. An unrelated younger brother with no name or standing had been dropped into his life for no reason. Though he knew there was no blood relation between them, he had brought plenty of trouble to his elder brother's otherwise smooth life. And it was thanks to his brother being ill every three days and seriously ill every five that he had a chance to get close to him.
The vast family estate fell into the younger brother's hands. Seeing his elder brother finally lose his composure, the younger brother felt indescribably pleased, body and soul.
Elder brother, my dear elder brother, you led me down this path, where we're neither lovers nor brothers! I'll give you everything, so please be a little kinder to me!
[Forceful, possessive younger brother who handles things with brute strength and acts like a dog, and his aloof, frail elder brother who relies on his wits]
[The brothers are not blood-related. The younger brother was adopted, though there was a misunderstanding about it]
