明日が休日なら僕と君二人きり。 する事はひとつな訳で
Does it still mean like the counter "ひとつ” here. Something like "one thing I want to do."?
Am I missing from my understanding here? I've only just learned how わけない is used.
Since tomorrow's a holiday, it'll just be the two of us. There's one thing I want to do.
する事はひとつだ means "the number of things to do is one", or more naturally, "there is only one thing to do". See: What does it mean to end a sentence with ひとつだけ?
～な訳だ/～という訳だ roughly means "naturally", "as a consequence" or "it's that ～", see: How to end a sentence in わけ And で is used instead of だ after 訳 because of this.
する事はひとつな訳で。
Naturally, there's only one thing to do (together).
Of course there is only one thing we should do.
