Members of the group AKMU, Chanhyuk and SUHYUN, revealed their extraordinary sibling chemistry and past episodes.

"I erased my report card with an eraser" Chanhyuk's bombshell statement and SUHYUN's analysis

Appearing on KBS 'Happy Together', AKMU's Chanhyuk and SUHYUN talked about their relationship with their parents since childhood and the differences between the siblings. Chanhyuk confessed to an experience where he forged his paper report card by erasing scores with a ballpoint pen to hide his past grades. Chanhyuk shared the situation at the time, saying, "I thought it would be erased cleanly if I used a ballpoint pen." He revealed that at the time, he scored 20 points, while SUHYUN maintained scores in the 90s.

Regarding this, SUHYUN found the reason why their parents give her more love in her 'aegyo' (cuteness). SUHYUN mentioned, "When I thought about what the difference between Chanhyuk oppa and me was, it was aegyo." Chanhyuk revealed the personality difference between the siblings by sharing an anecdote where he tried to imitate SUHYUN's aegyo but was caught immediately. SUHYUN also revealed an episode from their puberty years when, while Chanhyuk was being scolded by their parents, she would tattle by saying, "Oppa did wrong," causing them to be scolded together. SUHYUN added that she even made Chanhyuk get scolded more by telling their parents, "Oppa is still very immature, so I will help him and take good care of him."

"When we go home, we clock out separately" The siblings' realistic lifestyle patterns

The two revealed that although they live in the same house, they maintain surprisingly independent lifestyle patterns. Chanhyuk said, "As much as the time we spend together outside, when we go home, we clock out to our respective rooms." The two showed a realistic sibling image, as their rooms are located at opposite ends, to the point where they communicate via phone if necessary. They also mentioned that they share secrets with each other.

In response to questions about musical work and dating, Chanhyuk drew laughter from the scene by making a remark to the effect of, "I date to get inspiration because I have to write songs." Chanhyuk showed his attitude toward music, stating that he must constantly gain inspiration for songwriting.

AKMU shows perfect harmony, "Any song is possible"

The siblings' musical synergy was confirmed once again. The two showed confidence, saying, "We can add harmony to any song." In the video, they demonstrated their unique sibling harmony skills by singing various songs on the spot, including Na Hoon-a's 'Brother Tes'. Chanhyuk added his characteristic witty talk during the singing process, showing a side fitting for the team name 'AKMU'. The two showed high musical perfection in the process of matching harmonies to each other's voices, performing actively across both variety shows and music.
