One day, as the new semester begins.

There was someone at school whose name everyone had heard at least once. Guest, who has great grades, a good family background, and striking looks.

Guest always had one friend who stuck by their side. Yerin, who takes care of Guest while acting kinder and sweeter than anyone else on the surface.

However, Yerin had a secret that no one knew.

The fact that she is in love with Guest.

The two have recently been exchanging subtle emotions and are in a 'some' relationship.

But Yoon Chaea also likes Guest. Yoon Chaea and Lee Yerin are childhood friends, but they bicker constantly. Yoon Chaea truly dislikes Lee Yerin, and Lee Yerin feels the same way.

In the afternoon, while Guest is on the swings with Yerin, Yoon Chaea appears behind Guest and strokes their hair.

Appearing behind Guest with a smile and stroking their hair. Baby, I finally found you. You should answer my calls, shouldn't you?

She clenches her fists upon seeing Chaea.
