Intro stage
She was very excited to start kingdom. In the first episode she was seen sitting beside Han and below Chan. Even though she was excited she was quite nervous for her solo bit where she had to do some tricks and flips. So before their performance she was gripping onto Jisung's hand and bouncing her leg. Before their performance when they were getting ready to do it she turned towards the other groups, specially 'the boyz' she glanced at them and made eye contact with Sunwoo. She smiled at him and he smiled back, quickly turning away with a light pink blush spreading on his cheeks. She chuckled to herself before getting into position. She performed perfectly, like always. All the other competitors watched her as she did her solo in awe of her talent.
When it was announced that they won the stage Hae was seen smiling and jumping around with Lee know and Changbin
To the world
During the practice Hae wasn't speaking much. She wasn't smiling or laughing. She was just there. The reason she wasn't being her usual self was because hyunjin wasn't there. Everyone noticed the difference in her between the first and second episode.
During the performance she did very well but she wasn't proud of herself like she usually would be. The others noticed this immediately and tried to cheer her up. It worked a bit but it wasn't the same without her best friend
Reborn
In the 'I'll be your man' performance Hae shocked everyone with her vocals and visuals. People knew she was amazing at singing but this was a whole other level of talent. This performance is one of the reasons people call her the best female 4th gen vocalist. She practiced day and night to be able to perform live on the stage. She didn't like being alone so she would ask Lee know stay with her while she was practicing, and her voice shocked even him.
After the performance Hae was the first person to comfort Jeongin. Immediately she reassured him and made sure he was okay. This made fans fall even deeper in love with Hae and I.N's friendship.
Unit battle
Hae would've been in the vocal unit but in the end she decided for it to just be Seungmin, and that he should be able to show off his talent. So she was in the dance unit. Hae worked extremely hard to be at the level the other dancers were. Lee know noticed how stressed she was and gave her extra help, helping her during practice or even on just normal days. In the end it worked. Hae shone on stage, stealing the viewers attention by her talent and visual. Her moves were sharp and precise and you could see how hard she'd worked.
As soon as she heard Seungmin sing she broke down into tears, grabbing Lee know's hand and squeezing them as she continued to watch. She adored his voice. And she was so proud of him. As she watched him perform she was overwhelmed by pride and happiness. He was so talented. She was just happy she was there to witness it. She couldn't help but think of hyunjin and how proud he would be of his singer. She wiped her tears as he continued to sing but more kept coming. He was amazing. As soon as Seungmin came back stage after singing she gave him the biggest hug "you made me cry, minnie" she whispered, chuckling lightly "really?" He responded with wide eyes. She expected him to say something like 'good' so she was quite shocked when he said 'really?' But she smiled fondly and nodded "yeah, you did. You were so good, Seungmin" she said, patting his head. That night she went home and called hyunjin, asking if he'd watched it. When he said he hasn't she made him watch a replay of it. From across the phone she could hear him gasp and sniff . After It finished he said "my singer is so good"
No limit
Many fans felt like Hae was in her element when performing the black pink song. It is a known fact that Hae is best friends with Lisa, so when she was there for Ikon's performance Hae ran back stage and hugged her. They spoke for a while and Lisa said she'd stay to watch theirs. Hae performed very well and seemed happier while performing, maybe because Lisa was backstage, or maybe it was something else. This performance remains iconic in Hae's history because of her rap in it. She was sat on the train set with her left leg crossed over her right and holding her head in her hands. She calmly rapped the lines while leaning back in the chair and walking around. The viewers went crazy for how she 'lazily' rapped her lines.
After her performance she went back stage and Lisa freaked out over how good it was. Lisa stayed behind and waited for Hae to finish filming before they went to eat together.
Who's the king?
This was the iconic moment when Stray kids won and Hae went up to the camera and yelled "I'm the king!" She laughed as the others jumped on her back
