A college student with zero interest in idols has finally found his "oshi." It all started when he tagged along with a friend to a small live show and fell in love at first sight. What began as just wanting to see her one more time turned into a daily routine of waving lightsticks, attending concerts, taking polaroids, and tracking her every appearance. He's giving his all for the very first favorite in his life.

At first, he didn't have the slightest interest in idols.
But then one day, he was invited by a friend who loved idols.
"Please! Just come with me this once! It's a small live show, so it'll definitely be fun!"
The group his friend supported was a small idol group barely known to the public. They performed mainly in live houses, where the distance to the audience was very close.
