It had been a hard day - nothing but dance practice and singing lessons, all day long. As always, Sei threw herself into the work, always giving 110%. When they got back to the dorm, she rushed to be one of the first ones to get a shower. When she came out, she found Lua typing something on her phone, a devious grin on her face.   "What are you doing with my phone?" Sei asked.   Lua looked up but made no attempt to hide what she was doing. "Your message alert kept going off while you were in the shower. I helped you out by taking care of it." She finished what she was typing and hit send with a flourish before handing the phone to Sei.   Sei looked down at her phone, trying to figure out what Lua had been doing.   "You'd better hurry," Lua said. "She'll be here to pick you up in about 10 minutes."   "Who?" Sei looked startled as she looked up from the screen and into Lua's eyes.   "Lime, of course." Lua said, as if the answer should have been totally obvious. "By the way, we think you two make a really great couple."   Sei's mouth dropped open in surprise. "We?" Her brain was going in a million different directions at once, trying to process this new information, and it went to the first thing it didn't understand.   "My girlfriend and I," Lua said with a shrug.   Ordinarily having learned the gender of Lua's mysterious significant other would be a significant event, but right now the most important thing to Sei was to clear up this misunderstanding about her relationship with Lime. "We're not a couple," she said with a nervous laugh. "Lime and I. We're not a couple."   Lua raised an eyebrow. "Are you sure about that?"   Sei nodded, her face a study in fierce determination. "Yes, absolutely."   "Okay, okay," Lua said, raising her hands as if fending off an attack. "You're not a couple. But are you sure that Lime knows that? And either way, you need to be dressed and ready to go in just a few minutes."   Sei nodded and headed to her room. As she got dressed, she turned things over in her head. She and Lime weren't a couple, were they? That definitely seemed like something she would know, without Lua having to tell her. They'd just met a little over week ago, at the "All I Want Filming." They texted back and forth several times a day, but that was something friends do, right? And it didn't mean anything that they signed off their texts with kissy-face emojis. Sei kissed all her friends in real life all the time, so why wouldn't she online as well? And she and Lime had gotten together to hang out a couple of times, but that was definitely something friends do. It just gave Lua the wrong impression because they all had so few friends outside Weki Meki.   Sei was dressed by this time, so she headed to the door to put her shoes on and wait for Lime. The whole time, she kept turning things over in her mind. She was pretty clear that she and Lime weren't a couple. But was Lime sure of it? It occurred to her that it was entirely possible that Lime thought they were a couple.   How did Sei find out if Lime thought they were a couple? And what did she do if she did? Doyeon-unnie would know what to do. Sei rushed to the door of the small bedroom and knocked. Yoojung-unnie answered the door, her hair up in curlers and her makeup half-done.   "Sei! You look
