Singer Ailee and actor Choi Si Hun, known for his appearance on the dating reality show Single's Inferno, recently tied the knot — but it's a lighthearted moment from their wedding ceremony that's capturing the internet's attention.

The couple held their wedding on April 20, with numerous friends, fans, and fellow celebrities sharing glimpses of the celebration on social media.

One clip in particular, a special performance by veteran singer Baek Ji Young, went viral after highlighting the bride and groom's starkly opposing personalities.

Ailee was caught on camera singing along and dancing to Baek Ji Young's earworm "Candy in My Ears," getting swept up in the performance with high energy at full blast.

Choi Si Hun, who stood beside her, clapped quietly, his face beaming as he watched his new wife in her element.

Fans online were quick to point out the contrast, labeling Ailee a classic extrovert and natural performer, while praising Choi for his more reserved, introverted demeanor.

"The reactions to a performance showcase their personalities," one fan commented, adding a laughing emoji.

Another wrote, "She's the life of the party, and he's her biggest fan."

After the ceremony, the energy continued with music from Beyoncé playing in the background. Once again, Ailee rejoiced and danced in front of her groom Choi Si Hun, who was standing by the side and admiring her.

The moment has since been widely shared on platforms like Instagram and TikTok, where fans are celebrating the couple's dynamic as "the perfect balance."

Though neither Ailee nor Choi has commented publicly on the viral clip, it's clear that fans are loving the candid look at their relationship.

"They seem like the perfect couple," one user wrote.

Ailee, known for her powerhouse vocals and charismatic stage presence, debuted in 2012 and has released numerous hit songs.

Choi Si Hun rose to popularity as a contestant on Singles Inferno, where his quiet charm earned him a dedicated fan base.
