IU’s new remake Square’s Dream from her highly anticipated album A Flower Bookmark Pt. 3 is winning hearts online, not just for its nostalgic sound but for a viral moment starring none other than rapper Din Din.
A Sibling Throwback in Song Form
A post titled “DinDin’s Reaction After Hearing IU’s ‘Square’s Dream’.jpg” on Korean forum theqoo has racked up nearly 50,000 views, thanks to a candid Instagram Story from DinDin. The rapper shared, “It’s good……,” followed by a playful quip hoping that IU’s version would “cure his trauma” associated with the song.

Originally by W.H.I.T.E, Square’s Dream carries playful, almost teasing vibes, perfect fuel for DinDin’s self-deprecating humor. Fans quickly connected the dots, recalling DinDin’s past stories of being the youngest sibling and the chaotic energy that came with it.
His reaction hit especially hard for longtime followers who remember his on-air anecdotes about being the family scapegoat: ignored, teased, and still weirdly happy about it.
Netizens Can’t Get Enough
On theqoo, netizens exploded with laughter, drawing connections between DinDin’s past and the whimsical energy of IU’s track. Highlights from the comment section include:

- “DinDin’s the youngest in his family and people say he really was just like that ‘Din’ character LOL.”
- “Is this Stockholm syndrome or what?”
- “Whenever I hear Square’s Dream, I think of DinDin now LOL.”
- “I remember a recent viral post where someone said DinDin always got ignored, but felt a weird sense of belonging every time his sister hit him. I’m crying.”
- “I’m laughing way too hard right now.”
IU’s ability to breathe new life into a classic, paired with DinDin’s hilarious and unexpectedly touching reaction, has made Square’s Dream one of the most talked-about songs of the day.
