[he shrugs. no, he'd really not rather go to parties and the like, but - ] If it's better for you not to have me around during that time, then I don't mind staying out of it. If you want me there, then I'll try my best not to kill anyone.

[he'll do his best to be as polite as he can and not piss someone off in the process. it's not difficult for him to impose that terrifyingly calm persona onto his self when need be, but of course talking isn't really his high point and being charming to anyone is off the table, as much as he can manage to be polite. the reasons for him to be charming to anyone are quite few: when he's trying to seduce someone, when he's trying to piss off someone, or when he's pissed. perhaps in that way he's not really so different from 'provocation expert' count kuroo, but all the same, at least kuroo has the grace to be tactful about when and where to use it, whereas tsukki has the charm of a sharpened axe.]
