First of all LINE DISTRIBUTION I LOVE GROUPS WITH GORGEOUS LINE DISTRIBUTION

Second of all I still don't understand the stories behind the other three/four (Himchan's a bit unclear to me as well) members

Thirdly THE PHENOLPHTALEIN SOLUTION

I WAS LAUGHING SO HARD BECAUSE I SAW THE BOTTLE AND I WAS LIKE OMFG WHY IS THERE PHENOLPHTALEIN SOLUTION HAHAHAHAHAHAHAHAHA

THEN I FREAKING REALIZED

THE SOLUTION WAS USED TO WRITE AT THE BACK OF THE PHOTOS

SO WHEN DAEHYUN POURED THE ALCOHOL ON IT

THE ALKALINE DRINK CREATED A REACTION

SO THE PHENOLPHTALEIN SOLUTION TURNED PINK

AND HE COULD READ THE MESSAGE

HOLY

but fourth of all how come it worked when all he did was immerse the paper in tap water

nonetheless great music great video great plot great characters great actors (if Daehyun received a historical drama character as his acting debut that would be hilarious because V and Baekhyun both got historical drama characters as their acting debut lmao) great director great "chemistry" I thank Pn Too and Mr Leong for being such wonderful school and tuition chemistry teachers
