After much convincing, Hikaru agrees to play Isumi. However, he will play him for Isumi’s sake, not his own. He will not enjoy the game or get into it. He can’t betray Sai. But when the game of Go becomes intense, is there anything that Hikaru can do... (more)? Hikaru ties hard not to betray Sai. He promised him that he would never play again. But can it be helped? Will Sai ever return to him?
