章 626: There's No Way My Cute Little Sister Is The Ice Princess

(MC POV)

After that proud declaration from Tsuki, we returned back to class just as the bell started to ring.

"Tsuki-chan… I might be imagining things but… Did your breasts get bigger?" Maeda asked, looking pointedly at my little sister's chest area.

She smirked, "Hehehe~ I had a growth spurt and it's a cup size bigger than before! Jealous?"

I did my best to keep my face neutral and pretended not to hear them.

I caught Nishimura glancing towards Tsuki's direction, his eyes widening for a moment, before quickly turning away and pretending he did not hear nor see anything as well.

"Heeeeh~ I'm definitely jealous," Fujiwara groaned, looking down at her own chest. "Did you do something special to make them get bigger?"

Tsuki's eyes gleamed, her eyes darting to me for a moment before returning back to her friends.

No, Tsuki, don't say it...

"Fufufu~ It's all thanks to Aniue!"

"""Eh?"""
