As for the "lk21" part, I assume you're referring to the popular Indonesian movie streaming platform, LK21 (also known as Layarkaca21). If you're looking to watch "One Night Stand" (2021) online, you can try searching for it on LK21 or other streaming platforms.

Here's a brief review:

4/5 stars

The lead actors deliver impressive performances, bringing depth to their characters. Anissa Rawles shines as a strong and independent woman, while Frederik Alexander brings a charming yet troubled vibe to his character.
