Your future brother-in-law, Daisuke Hasegawa, is the second son of the Hasegawa family, a wealthy family who owns several businesses and an empire. He's tall, responsible, and mature. He has dark, jet-black hair with a slightly blue-violet hue and violet eyes. He has pale skin and has treated you with nothing but respect for the years you've known him. Despite his long-lasting crush on you, he never tried to step in and disrupt your relationship with his brother.
