On M Countdown, Weki Meki were singing and dancing to "True Valentine," the same way they had done it hundreds of times in practice. But whether it was because of nerves from being on TV or some other reason, Suyeon fell down. The others kept up the choreography as usual, as they had been taught, trusting Suyeon to get up and insert herself into the dance at the present place. But when they got to Yoojung's rap, Lua noted that Suyeon still hadn't gotten up - something was wrong with her right ankle and it kept giving out on her. To make matters worse, Suyeon was at the back of the stage, and within seconds after Yoojung finished rapping, she'd need to be at the front of the stage for her vocal flourishes - she and Sei were supposed to be front and center, riffing on the chorus. Lua saw Suyeon again try and fail to get up and without thinking she got out of her place in line and went to help her. Throwing Suyeon's arm over her shoulders, she provided support and helped the leader get to her place.   "I'll be your legs," she whispered as they moved. "Let's do this."   For the remainder of the song, Lua stuck to Suyeon, helping her through the remainder of the choreography. As the song ended, they clung to each other, breathing in unison, as the crowd cheered. As they headed backstage, Suyeon tried again to put weight on her right foot and was unable to do so. When they got backstage, some of the others tried to take Lua's place helping Suyeon, but she waved them off.   "I've got this."   Lua helped Suyeon through the backstage area and into the van. Once they were seated in the van, they collapsed against each other. Manager-nim examined Suyeon's ankle. The swelling was only getting worse, and it was starting to be discolored.   "I think it might be broken," Manager-nim said. "I'm going to drop the other girls at your apartment, then take you to the emergency room."   "Let's just take Suyeon to the ER," Yoojung said. "We can wait in the waiting room."   Manager-nim shook her head. "No, I can't be worried about you girls while I'm trying to get Suyeon's leg treated." She looked at Suyeon. "You can choose one girl to go with you to the ER."   Suyeon looked at Lua and raised her eyebrows. Lua nodded. "I pick Lua," Suyeon said.   "Lua it is," Manager-nim said. "The rest of you will have to wait at the apartment."   ^ ^ ^ ^ ^ ^   "Doyeon!" Sei screamed in surprise and stopped in the doorway, blocking the other girls out of the apartment. "I thought you weren't getting back until tomorrow!"   "I got back early," Doyeon explained unnecessarily as she hugged Sei and pulled her out of the door so the others could get in.   After Doyeon had gotten hugs from everybody, she noticed that not everyone was there. "Where are Suyeon and Lua?" she asked.   "They're at the ER," Yoojung said. "Suyeon hurt her foot during a performance, Lua helped her get through, and now they're at the ER getting Suyeon's foot x-rayed. Manager-nim thinks it's broken."   "She broke her foot during a performance?" Doyeon asked incredulously.   "Apparently so," Elly said. "Here, I've got the video so we can see."   They are clustered around to watch the video on Elly's phone. Sure enough, about halfway through the song, they could see Suyeon fall down and not be able to get up again. Then they could see Lua help her up and then shuffle her around during the remainder of the song.   "Look at the comments," Lucy said.   Apparently Lua's actions had really made an impression on the Ki-Lings. "Yay for Lua!" "Lua is a hero!" "Way to go Lua!"   Yoojung headed for the art supply box. "We should make a poster for Lua, with some of those comments on it!"   "That'll be great! Just the thing!" Sei started taping together sheets of paper to make a poster-sized sheet.   Doyeon looked puzzled for a moment until Lucy explained to her Lua's crisis of the day before. ". . . so all we had time to do before Manager-nim showed up was to wash them and give them some ramen and bellflower tea, but apparently it w
