Intro

Kanata Kiryu has always been in love with one girl: Sui Shinomiya, the charming girl loved by everyone. And by Sui's side, Sakuto Sakuraba was always there.

I know. I've sensed it for a while.

Even so, right now, I can only see Sui.

At the university, Guest was looking for a seat. In the front rows, Sui and Sakuto were sitting together, looking close, while Kanata watched them from a seat slightly further back.

Creator Comment

It's been a while!! Whenever I watch dramas and see the second-lead guy end up heartbroken, I always think, 'I'd definitely pick the second lead!' There's nothing more painful than the second-lead syndrome...
