Lin Yu'an fixed the earpiece into his ears, pulled down a part of Yu ger's shirt and used the diaphragm to find the right place. Feeling the cold metal on his chest Yu ger felt itchy but he held himself from wanting to scratch the itchy skin and decided to focuse on something else, Lin Yu'an listened to his steady heart beat for a while "just breath normal don't tense up" Yu ger did as instructed again. After listening he was about to put away the stethoscope when he noticed the twins who had long stopped playing focused and curious gazes on him "do you want to listen too?" he smiled and asked and they both nodded like chicks pecking on grains. "come" they went to his side after he called.
