The two singers decided a fall picnic would be nice, and they set off to the park, where Eric Nam revealed it was his brother's birthday. He then video called his younger brother, who's 8 years his junior and lives in the United States.
After introducing Solar, Eric Nam's brother asked, "Do I call her sister-in-law? Sister-in-law," to which the MAMAMOO member responded, "Brother-in-law." Despite her limited English, she did her best to wish him a happy birthday.
On the same episode, Solar prepared a special prank for Eric Nam at a clothing store. An employee kept making negative remarks about Solar, which she responded to angrily. Eric Nam tried to deal with it calmly, but he definitely felt awkward. Solar then told him it was just a prank!
