expression
I don't care; fine, whatever; that's okay; sure, go ahead
Casual phrase used to express indifference, reluctant permission, or mild dismissal. The trailing けど softens the statement, leaving room for the listener's reaction. Often used when the speaker has no strong objection but isn't enthusiastic.
「これ、食べてもいい？」「別にいいけど。」
"Can I eat this?" "Sure, go ahead."
「遅くなっても大丈夫？」「別にいいけど、明日は早いよ。」
"Is it okay if I'm late?" "I don't care, but tomorrow's an early start."
