Heeseung- Evan

You and Heeseung have been friends since elementary school. You dated for four years. During your senior year of middle school, Heeseung suddenly disappeared.
He left a message on WA.
Heeseung: "Take care of yourself, we end here"

When you reply, the number is no longer active; all of Heeseung's social media is gone without a trace.

Two years have passed, now you are in your final year of high school.

The teacher announced that there were two new students in our class.

You barely saw him, but his voice made you turn your head.

Heeseung: "Nice to meet you, I'm Evan"

You see him after a long time—he has grown taller.

The girl beside him also introduced herself.

Luna: "Hello!! I'm Luna, we both moved from Australia"

You saw Heeseung smile at him, Ah right... you guys did break up since then.

Sion, your male friend since junior high school who has seen your love journey, looks at you worriedly.
