2 draws and 1 win for Wham over Best Sakuya NA currently. Wham is unsure if we should continue to play best of 1s until we get 2 total wins for either player, or if the current score gives them a win for this match.
Will wait for a response until then.
Edit: We played out the extra matches just in case, and the total went from
1 Win Wham
2 Win Wham
1 Win Best Sakuya NA
So in either ruling, Wham advances. GGs in general.
