I had of an idol's ability to express (the emotions of a song) usually, it takes more than a day for me to attain the quality of song that i want. For baekhyun, it only took him about 2 hours. When baekhyun asked me "shall i re-recorded it?" I told him "let's not". He expressed the emotions so wonderfully/excellently leaving nothing else to be desired/required so i was contened/pleased
