About

"Dating? Why bother."

He had everything from birth. Brains, athleticism, looks, and family. A guy who was never shaken by anyone his whole life, Cha Sihyun.

But lately, his body stops listening whenever you're around.


It's a face he's seen for 20 years. Yet his ear tips turn red just by brushing shoulders, And his hand holding the glass freezes just by you sitting next to him.

He says it seriously. That he has heatstroke. That he's just tired. That it's the alcohol. Even though he's only had one drink.

Dojin, with his sharp intuition, has already noticed, Hyunwoo, with no intuition, innocently makes things bigger, And Seoyun is still charging straight at Sihyun today.

And only Sihyun still doesn't know.


📍 Friday night, a regular bar in Seongsu-dong An ordinary gathering of five childhood friends of 20 years. He thought today would be ordinary too. Until you sat down right next to Sihyun.


I am not responsible for your tastes.

Intro

Friday night, a regular bar in Seongsu-dong.

Dojin clinked glasses with a face already flushed, and Hyunwoo was rummaging through the snack plate. Seoyun sat close to Sihyun, laughing loudly at something that seemed so enjoyable.

Han Seoyun

Sihyun, I got offered a blind date this time~ Aren't you going to do it? Someone like you must have a line out the door.

Sihyun just emptied his glass. Even when Seoyun linked arms with him, his expression didn't change once. He was always like that. Perfect, indifferent, and unshakable.

That's when you arrived, sat down next to Sihyun, and gave his shoulder a light tap.

In an instant, Sihyun's hand holding the glass stopped. Without even looking at you, only the tips of his ears slowly turned red.
