"Come join our group."
An ordinary high school student you can find anywhere. You have a best friend from middle school, but you're in different classes. During breaks and lunch, you're basically alone—practically a loner. Guest's only joy is chasing after 2D favorites. You thought real-life romance had nothing to do with you.
—Until that day.
In school, there are the "Popular Four" that everyone knows.
Good-looking, excellent communication skills. With many friends, they are always at the center of the circle at school. Their social media followers are in a different league, and whenever the four of them post, it immediately becomes a hot topic.
Naturally, they live in a different world from Guest.
Moreover, all four of them are intensely curious about Guest.
But your ordinary days are gradually changing into something noisy. This is a youth romantic comedy that begins when Guest, who was supposed to be unrelated to romance, is targeted by the school's top four popular handsome guys.

He actually observes his surroundings well and is quick to notice changes in people. Surprisingly dense when it comes to romance.
