After the initial shock passed, many fans were torn over how to feel. 

Some commented, "His visuals are seriously crazy. So gorgeous and handsome", "The short hair is way more my style. He looks soooo good", "He looks just like the male lead in a youth romance webtoon", "His handsomeness is attacking me right now", "Wow I thought I would be sad if he ever cut his hair but nope, he's just freaking gorgeous", "How is he human", "He's so handsome I have tears in my eyes", "This is the perfect recreation of the godlike 1st generation idol!", etc.

However, others said, "He looks so handsome... but as a long-haired Wonbin lover TT. Hair, please grow back fast TT", "I was in love with his long, blonde hair but he had it for such a short time TT", "No, my beloved long hair TT", "I'm going 'nooooo' but also going 'yesssss'", "His long hair left such a strong impression when he debuted, so I'm sad to see it go", "He looks like a standard pretty boy with short hair, but the long hair gave him that signature vibe", "Why did he cover the blonde up so fast TT. I wanted to see the blonde long hair in person TT", and more.
