My new Neighbor's an Idol!?

Figure out

Another new day, another upcoming study session that Ishi was dreading. Honestly, just what was that girl thinking, inviting Rinse like it was nothing. Why would she want to do something like that was beyond him. Chinae seemed to be the last person to care about idols. Perhaps he had gotten her wrong after all and that she was not different from their fellow classmates.

Unless she wasn't enamored with the girl. What if he was reading into it wrong and she actually had a trap planned? That certainly seemed much more up her alley. That could explain why she appeared to be a lot nicer to Rinse than literally any other person he saw her interact with.

Ishi was going to have to stay on his toes around that girl. He might not have cared about whether Rinse got hurt or embarrassed. But chances were that a potentially harmful plan could also affect him as well. Vigilance was key here. Though he wasn't about to tell either of the girls about his suspicion. Not without evidence at least.

Soon there was a knock on his door. Rinse had made her return to his house as he let her in. Right after that, Chinae arrived. They set themselves up the same as yesterday with all the homework strewn across the coffee table.

"Since I'm here, I should be helping you out too." Rinse offered and to his surprise, Chinae accepted without hesitation. If that girl wasn't going to be resistant to her, than his presence was pointless. Of course, Ishi would still lend a hand. Things might be a problem if it came out that he offloaded the work to someone else. Or not, who knows how much the teachers actually cared about this setup given their lackadaisical natures.

"Thanks, that makes a lot more sense now." She expressed her gratitude. Now he could tell for certain that she was acting differently here. Rinse wouldn't have noticed since this was the second time she had ever met the girl. So to her, this was normal.

"Don't leave me out of it." He spoke up, telling them that they should take turns so that this would go by much faster.

"Great..." Chinae's mood took an 180 as he sat besides her. "Go ahead then."

"Since I'm not doing anything, can I go to your kitchen to grab us all refreshments?" Rinse asked him. The nerve of this girl, he thought. Who was she to think that could give away his family's drinks to someone he didn't like. Despite the personal objection, he didn't reject her request and she left the pair to work on some math questions. This allowed him to make his move.

"So, what's your plan?" He asked her bluntly.

"My... Plan?" She raised an eyebrow to his question. Her face appeared to be bewildered at his apparently random question. "To finish all my homework today?"

"I mean with Hattori." Her hand's grip onto the pen tightened when he mentioned the name. The girl's normal confidence seemed to disappear before his very eyes. "I know who you really are."

"You... You do?" Her voice quivered as she spoke. Now he was certain she was cornered by him.

"Of course. You're always so mean to everyone. Until you met her." He explained his thought process. "So clearly you looking to get her to lower her guard. Then you'll strike when the time's right."

"Huh?" Immediately she relaxed when she learned of what was going on in mind. Then her mouth contorted into a mischievous smirk. "Oh I see what this is all about. You're jealous of me."

"Jealous?"
"Yeah. I bet your jealous that Hattori likes me more than you." She chuckled. "I never took you for the type to have some silly crush."

"No I don't." He defended himself. "And it certainly wouldn't be on her of all girls."

"I'm back~" Rinse returned with a tray in a joyful mood. On top of it was three cups of iced tea. "Were you two talking about anything interesting?"
