새벽감성

3 AM, the time when your heart swells for no reason. It’s okay if it feels a bit cheesy. "3 AM Sensibility" is a diary app for those with "middle school syndrome" vibes where you leave the sentences of that moment in your own private space and select only the ones you are confident in to display in the public square under a pen name.

My Space — Dawn Records Seen Only by Me

You can leave text and photos together, and edit, rewrite, and delete at any time. Only you can see the writing in your space. The "Today's Writing Motivation," which changes daily, opens the first sentence, and writings from 30, 100 days, or one year ago today will be retrieved via the "Black History Time Capsule."

Sealed Letters

Seal letters you send to your future self. They will open with a notification when the designated day arrives.

Post in the Public Square with 1 Pencil

Post only the writings you are confident in from your space to the public square using just one pencil. Only your pen name and title are displayed instead of your real name. You receive 5 pencils when you first start, and one more for checking in every day. Pencils can be used for 24-hour boosts, card themes, changing pen names (the first one is free), and sealed letters. Pencils are activity points used only within the app and cannot be purchased, refunded, or transferred.

Three Reactions, Rising Titles

Dawn Sensibility +1 · Goosebumps +2 · Black Flame Dragon Awakening +3. As reactions accumulate, your Chuunibyo Index rises, and your title changes through 9 stages, from "Sentimental Sprout" to "Legendary Chuunibyo Demon King." You can also leave short impressions via 100-character replies.

This Week's Chuunibyo King and Hall of Fame

A weekly ranking starting anew every Monday, a Hall of Fame for accumulated scores, and the most beloved legendary posts. Once the weekly tally is complete, a badge remains on your pen name profile.

Share Cards and Tags

Turn your posts into night sky card images and send them to friends. You can choose to display your pen name and include a photo, and change the atmosphere with card themes such as "Before Dawn" or "Inky." If you add tags like Rain, Dawn, Breakup, Unrequited Love, or Dark Flame Dragon, posts with similar sentiments will be grouped together. You can check replies, reactions, and weekly summaries in the notification box within the app.

Safe Plaza

Profanity, contact information, and links are filtered out before uploading. Once uploaded, posts and photos are checked by the server, and any issues are automatically hidden. Posts with 3 accumulated reports (1 for posts with photos) and reported replies are also automatically hidden and reviewed by the administrator within 24 hours. Newly created accounts can post, reply, and reaction to the Plaza starting 10 minutes after signing up. Accounts that violate the rules will have their usage restricted, and users you do not wish to see can be blocked immediately. Available for users aged 14 and older.

On Nights When You Are Feeling Difficult
