Need urgent answers...

[Sealbreaker]

How dual login works?
In KR version it available I guess.
My real question is...
Can I use same account to access seal online in 2 different PC (Not same PC) with same ID and same password but use different characters while playing?
I really need this answer, because my gf and me, we wanna play with same account.

Is that even possible?
If it is possible then is it legal to play like that?

Is it possible to use couple system, like couple 2 chars from same account? Male and female char obviously.


Another thing I wanna know is...
Can I assign certain keyboard keys on PC mouse, like picking up item key or even skill number keys?
Since the mouse I'm using has extra keys.
Is that legal to do so?
Since there is such an option available legally from Microsoft, so I want know if such a thing is even acceptable as per Seal online play rules.


I don't want to do anything illegal in Seal online so I need answers for clarification.
