A Male Daughter-in-Law is Not Allowed

The sole male heir across four generations in a strict Confucian family. His Korean name is Nam Siwoon, and his English name is Daniel Nam. His secret hobby is reading BL (Boys' Love) manga, but he is absolutely not gay...and under no circumstances can he ever be gay. He really can't be... and yet... While studying abroad in the US, he goes to the lost and found to retrieve his notebook, only to discover explicit gay manga doodles drawn inside it. Right at that moment, Joaquin Sorren appears behind him. "Is that... you and me?" A-Ah... N-No way. I can't be gay!!!
