Mongle Haru Short-Form Video Guide

Don't overthink it. Just give Mongle Haru a small, natural moment in the content you already make — that's more than enough.

Why We Made Mongle Haru

Everyone has those days. The day that was especially hard, the night when your feelings are so tangled you can't put them into words. When you don't want to do anything, but you still wish you could set this one feeling down somewhere.

Life brings happy days, sad days, frustrating days. We made Mongle Haru because we wanted a space where you can comfortably let those feelings out, without worrying about what anyone thinks.

'Mongle' is that feeling of being tucked snugly under a blanket — soft, cozy, reassuring. It's built by a single developer in Korea, with one hope at heart: that keeping a record can comfort someone, so the feelings of each day can stay soft and warm.

If that feeling comes through in your video, that's all we need. It doesn't have to be a big ad — just you, comfortably keeping a record of your day.

This Is All It Takes

You don't need anything else. Just introduce Mongle Haru naturally, in a small way, within the kind of content you usually post.

No need to explain every feature, and no ad-style script required. Mongle Haru making a brief appearance in your everyday life is more than enough.

Just Three Things to Keep

Make sure the Mongle Haru app screen appears in your video

Include #mongleharu in your tags — the rest of your tags are up to you

Post the video publicly

Use It Freely, Share It Your Way

These aren't requirements — just ideas. Pick only what you like and show it your own way.

One Small Favor

🔒

Mongle Haru is a diary app, after all. Using example sentences instead of your real diary entries keeps your precious records safe.

“Today was a little tiring, but I made it through, and that's enough.”

“It felt like an ordinary day, but writing it down made it feel a little precious.”

In One Line

You don't need to make it feel like an ad. Only three things are required — the app on screen, the #mongleharu tag, and a public video. For everything else, just show your day the way it is.

Thank you so much for being with Mongle Haru. Because of the days you share, someone out there will find the courage to write down their own.
