Why it worked
The video leverages a relatable scenario (finding a crush) within a popular app (Hily) to create a short, engaging, and positive user experience, making the app seem appealing.
Product placement
Hily: an app for dating and meeting new people. It ACTS as a dating app, allowing users to find and connect with potential partners. Removing it would change the video's premise. HilyApp: the name of the app, appears as a hashtag. It merely APPEARS. Removing it would not change what happens in the video.
