The 21-year-old admitted he felt slightly disheartened about missing the opportunity. Supporters quickly responded online, calling him "adorable." One X user commented:
"He is so adorable 😍 I hope some day he meets his living inspiration. Wow! What a moment that would be!"
Many noted how common it is for junior idols to feel hesitant around seniors, while others hoped he would get another chance to speak with him.

"This is gonna be very hard bc myung jaehyun, although is very friendly and extroverted, is the shyest boy infront of ppl he admires and jungkook is at the top of the list… and jeon jungkook is just... a shy boy ..🥹💜🩵," a user mentioned.
