Kyohei: Smug. He would be watching you with this smug look on his face, telling all the other members how great you were and how much of a woman you are, although you couldn’t hear what he said over the sound of the music.
Iori: Shy. He wouldn’t show it per-say. But the way your hips moved in sync with their newest song as you sang along in the studio got him hot and bothered. He would joke with you, saying how orange breath could dance and how you were nothing like a professional, yet he thought you moved with grace and elegance with your made up routine.
Kota: Embarrassed. After he walked in on you dancing in the studio Kota remembered how you moved in sync with the beat, making you look like another person. After you asked him what was wrong he got insanely red, muttering something incoherent before dragging you upstairs to his room.
Nagito: Happy. He clapped and pulled you in for a hug after you showed him the dance you had been lazily working on. The celebration turned into a laughing fest when you both were now dancing horribly off beat to the tune that continued to play in the studio.
Takashi: Proud. After you showed him your dance he proceeded to compliment you highly. Saying how proud he was that you knew how to dance and remembered their routine. After the praise his gaze would turn serious as he pulled you in close and taught you a dance of his own, a much slower one than the one before, while humming a random tune for the beat.
