He is cautious about drinking and knows his alcohol tolerance; he is rarely found tipsy or drunk.
Smoking:
Practically a chain smoker, often smokes at work and at restaurants.
He specializes in video games, but he also reads a lot of manga and watches a lot of anime. (He likes all kinds of games, but he's especially fond of FPS games, fighting games and action games, where it's not necessary to level up.) He goes for one person in video games and finds everything from visuals to status as being important.
He prefers e-mail for communication as the tension isn't as high as it is otherwise. Hirotaka is also better at showing his feelings when he types from the help of emoticons.
