Fans have been falling in love with Stray Kids' Hyunjin more because of his gentleman acts toward ITZY's Yeji.

The duo has known one another since they were still trainees at JYP Entertainment. Now, they have both successfully debuted under the said agency, being part of the rookie groups Stray Kids and ITZY. And the two continue to achieve more feats together with their fellow members.

As they look at the singers standing by each other, the fans couldn't help but notice their similar features, particularly their visuals and smiles. Considering their similarities and the fact that they both are 2000-liners, plus they exist with the same surname, Hyunjin and Yeji have been called the "Hwang Twins." They are even compared to the adorable dragons in the movie "How to Train Your Dragon 3: The Hidden World." Hyunjin is said to resemble Toothless, the male night fury, while Yeji is the female light fury.

But there are more reasons as to why they got the nickname. Like siblings, the two are very close to each other on and off camera. Luckily, fan cams were able to capture a few special moments of the Hwang Twins, which are mainly showcasing Hyunjin being a gentleman to the female artist.

One time, Yeji had to hurry off for her group's performance after MC-ing. Since she had no enough time to put the microphone and cue cards somewhere safe, she had to leave those at a random spot. At that time, Hyunjin was also about to get off the stage, but thankfully he took notice of this and went back to get her belongings. Upon seeing this scenario, fans have praised Hyunjin for his good act toward his labelmate.

In another situation, Hyunjin and Yeji were spotted sitting beside each other outside while having downtime from MC-ing. The former stood up to get something to drink, but before leaving, he saw to it that he asks Yeji whether she would like one as well. The latter was seen nodding her head, and Hyunjin went back with two bottled water for each of them. Once again, the male artist received lots of compliments from the fans and netizens.

These fan cams are solid pieces of evidence of Hyunjin's attentive and thoughtful side, as well as the pair's true friendship; no wonder they are dubbed "Hwang Twins."
