You're referring to the popular Japanese phrase "ウィンウィンしてる場合じゃなかった" (Win-win shiteru keshika janai)!

For those who may not be familiar, this phrase is often used to express that someone is being overly optimistic or unrealistic about a situation. The literal translation is "It's not like you're always winning, right?" or "You're not always coming out on top, are you?"

In essence, it means that things might not go as smoothly or easily as one hopes, and that there could be unexpected challenges or obstacles ahead.

So, if someone says "ウィンウィンしてる場合じゃなかった," they're cautioning against being too confident or assuming a best-case scenario will always unfold! 😄
