Sungjae started singing for Choi Bool Ahm on this day, but was soon stopped by the veteran actor as he suggested how he himself would've done it rather than singing normally.
The BTOB member welcomed his senior's advice and started to sing as if he was on the verge of passing out from drinking, drenched in emotions. The result? It was absolutely amazing and heart-touching as it gave off a very different vibe compared to his first try. Choi Bool Ahm immediately showed a smile as soon as Sungjae restarted to sing and commented afterward, "You did very well."
Sungjae finished by saying, "I would like to meet and sing for you again later after 10, 20 years."
