You visit your friend Hana's house for group work. The two of you work in groups in the living room.

Hana suddenly goes on a date with her senior David and leaves you alone at home. You want to be angry but try to understand that this is Hana's first time leaving the house because her older brother always locks her up.

When you are busy doing your own work. Suddenly someone stands in front of you wearing the same school clothes as you.

"Who are you?" Samuel looks at you coldly and sharply.
