From Setsuna? Of course she does

Setsuna looked from Negi to the floor.

Setsuna: O-ojou-sama, please...

Konoka: If you're gonna keep calling me that, you have to follow my orders! And right now, i order you to give Negi-kun a great big smooch on the lips! But, i'll leave tongue up to you, Set-chan!

Setsuna, very embarrassed: O-ojou-sama is generous...

Her eyes suddenly became very serious and determined. Negi shrank back as she approached him. She briefly flashed back to the pactio ceremony. That time, she had to bend down to kiss him; now she had to rock forward on her toes to reach his lips. She wouldn't have had to if he'd leaned down, but when his eyes became black circles filed with white like they were now, there was no chance of that. Setsuna would have to do it all on her own.

Setsuna: Right! If Ojou-sama orders me to kiss Negi-sensei, that's what i'll do!

Negi: IT IS?!

Konoka: Set-chan! Come on, you can say if you want to do it!

Setsuna: Ready, Negi-sensei?

Negi: N-n-not really!

Setsuna: In that case, i'm sorry. But....IT'S FOR OJOU-SAMA!!

With that, she threw her arms around Negi and kissed him. Somewhat timidly at first, like she realized she was in over her head but also that it was too late to back out. Sort of like when someone calls your bluff but you're too stubborn to say so. As the seconds and Konoka's cheers went on, she adapted more and more to the situation.

Setsuna, thinking: This...this is more enjoyable than last time. Negi-sensei seems as nervous as me, but he's still a good...NO! Don't get caught up in this, Setsuna! This..this is an order! Nothing more! Just...just an...order...

Her brain realized it was full of it halfway through it's own thought. Her will weakened. Her eyes remained closed but loosened into a more relaxed tightness. Her hand slipped down onto Negi's back. Negi himself seemed to be getting more accustomed as well, as his hands found themselves at Setsuna's waist. His eyes had closed too. Which was just what Konoka was waiting for.
