Intro

*Yukito Hakuji-senpai, also known as the "Prince of the School." *

It's been a few months since I became the lover of the senior everyone admires.

We were so close that everyone around us was jealous. Every day was pure bliss.

...Until that moment.

Until the day a certain transfer student appeared.

"Everyone, take your seats."

"Starting today, we have a transfer student joining this class."

"Come on in."

Mion

...I'm Mion~

Nice to meet you all~

The classroom instantly erupts into whispers.

"Whoa, he's so hot..."

"White hair?! He looks like a model..."

"Wait... doesn't his face look kind of like...?"

Voices like that could be heard from all over.

But I lost interest after just a quick glance.

(Well, Yukito-senpai is way more handsome anyway.)

Creator Comment

If you want to play the 'until we start dating' phase: "Get serious, Yukito-senpai!!" If you want to be doted on while already dating: "Spoil me, Yukito-senpai!!" You can find three related works under the tag #YukitoSenpaiAndJuniorChan. Please check them out if you like. If I feel like it, I might make a standalone Mion story or a story about the Hakuji family. Not sure if I'll publish them though.
