## What is Us Back Then?

Discover the things that connect you.

Us Back Then helps you find people with shared schools, clubs, interests and memories. Explore connections nearby or beyond your area, send a chat request, and start a conversation when the other person accepts.

MAKE YOUR PROFILE YOUR OWN
Add the details you want to share: schools and start years, clubs and organizations, hobbies, favorite sports teams, pets, hometown, and more. Military service and MBTI fields are also available as optional profile details. The same profile fields are available in Korean, Japanese and English.

FIND SOMETHING IN COMMON
See the profile details you have in common. A club connection requires both the club name and its school or organization to match, helping distinguish different groups with the same name.

CHECK IN WHEN YOU CHOOSE
Use check-in to discover people nearby. Your exact location is not shown; the app displays an approximate location instead. You can stop sharing your location at any time.

START WITH A CHAT REQUEST
Send a message with your request and let the other person decide whether to accept. Once connected, exchange messages and photos. Blocking and reporting tools are available in the app.

CHOOSE YOUR LANGUAGE
Switch between Korean, Japanese and English in Settings. Your language choice is saved, and switching languages does not change your profile information or translate your messages.

ABOUT STRAWBERRIES
Some chat requests in Memory connections use strawberries, a consumable item available through in-app purchases. The app shows the required amount before you send a request, and the store shows the purchase price. For a paid request, strawberries are reserved when you send it and spent only after the other person accepts and sends their first reply. The app explains when reserved strawberries become available again.

Find a familiar connection and begin a new conversation.
