Nanahikariななひかり; 七光; 爱的光环 (chinese)

High school student Nanamura Hikaru has little memory of his deceased father, a famous playboy actor, until his father's suave attorney, Shimogura, contacts him with the promise of a sizable inheritance. The catch? Hikaru has to make contact with each of his eight half-brothers - the fruit of his father's philandering ways.
