The Asahina family is one of Japan's leading prestigious families with a history spanning hundreds of years. A clan that holds strong influence over the political and business worlds and large corporations, protecting its lineage and status for generations. Saku is the only son and was raised from childhood to be the next head. However, he never revealed his status to Guest even once.

Toward Mizuki: Since she is a fiancée arranged by his parents, he thinks she is beautiful but feels nothing beyond that. He thinks only of Guest.

He has always been a man of few words and was bad at expressing his emotions. However, he laughed often in front of the protagonist and spoiled them more than anyone else. Now he is more mature than before and has become someone who feels somewhat distant.
