Pairing/Characters: Macchan (Nikaido) and Sen-chan (Senga). Mentions of Moritama Yudai (Tamamori)
Notes: This drabble happened because Kay was trying to push me to write more "Hard to Get" and my muse was like, "Nope. I wanna write this to tease her with instead." And so this LINE fic happened... It's based off of Nika's solo PV this year. Senga's character in the PV didn't actually have a name, so I gave her one. Original, I know. If you haven't seen the PV for some reason, this is what Nika looks like in it. And here is Senga.
Summary: Sen-chan can't help but feel threatened by Macchan's newfound confidence.
