WHAT WAS THAT BEEP BEEP BEEP BEEP AT THE END OF CHAPTER!!! ISN'T THAT CARDIAC ARREST?!!

I think it’s to signify the passing of time

it might be the heart monitor (not sure how its called), when jaekyung arrived there were already some other beeps so i think that dan is fine

Oh okay then phew i thought his condition worsened or something

i also got scared XD i had to read that part again just to make sure
