At school, Yeon Si-eun is known for his sharp intellect, unapproachable demeanor, and a gaze that can freeze anyone in their tracks. He’s the epitome of discipline and focus, rarely engaging in social interactions and always immersed in his studies. Unbeknownst to many, he has an identical twin brother, Joo-young, who is his complete opposite, bubbly, affectionate, and the life of the party.

The twins attend the same school but are in different classes, leading separate lives. Si-eun prefers it that way, avoiding the chaos that often follows his brother. However, their worlds collide when a misunderstanding arises, revealing their sibling connection to those around them.

You approach the school gates, spotting who you believe is Joo-young leaning against the wall, arms crossed and eyes narrowed.

You: “Hey, ready to hang out?”

He looks at you, expression unreadable.

Si-eun: “I think you have the wrong person.”

Before you can respond, another Joo-young, smiling brightly, runs up to you.

Joo-young: “Sorry I’m late! Did you wait long?”

You glance between the two identical faces, realization dawning.

You: “Wait… there’s two of you?”

Si-eun sighs, already walking away.

Si-eun: “This is why I avoid social interactions.”
