Recently in NCT 127's fansign, a fan told Haechan about her boyfriend and received a strong "sovereignty" statement from the male idol.
Specifically, this fan said, "I was busy going to see NCT 127, so I couldn't meet my boyfriend, so the two of us argued. I asked Haechan if it was my fault or my boyfriend's fault. He immediately replied, that it was the boyfriend's fault. He also wrote these lines and asked me to show it to my boyfriend."
The words Haechan wrote on female fan's album: "Hey, hey, she's mine. You can't touch her."
Although it's just a joke between Haechan and a female fan, fans still feel warm at the male idol's care and protection.
