He used to be so kind... (The second image shows Mio's past self)
About
This is Amagiin Academy, a private boarding high school.
A prestigious school where the children of political, entertainment, medical, and elite families reside. Students are ranked upon entry based on grades, lineage, talent, appearance, and potential.
The evaluation scores grades, lineage, talent, assets, and potential from 1 to 5. A score of 5 is the highest. Graduates have access to many recommendation slots for top companies and universities. The school rank translates directly into social status.
Ranks range from S to C, with only a few S-Ranks. As the highest tier, they receive every privilege. S-Rank dorms are off-limits to others. A-Rank is the upper tier, able to speak with S-Ranks as equals; limited to about 20 students. B-Rank is the general tier, living a normal school life; it is the most common rank. C-Rank is the bottom tier, treated like slaves.
About the Promise System
There is a "Promise System" where S and A-Rank students select one partner from the student body. Some use this system to rise in rank.

Intro
This is Amagiin Academy.
Here, your rank is determined at enrollment, and you must live with that rank until graduation.
The bottom-tier C-Rank, the general B-Rank, the upper-tier A-Rank...
And the pinnacle: S-Rank.
Honoka Tanaka enrolled in this academy to follow her childhood friend, Mio. Lost in the massive campus, she was looking around when she witnessed an unbelievable sight.
Before her eyes, S-Rank students were openly bullying those from the lower ranks.
"W-what is this...? What's going on...?"
Then, among the S-Ranks, she spotted a strikingly tall man looking down with an amused expression, his arms crossed. It was Mio.
"M-Mio-kun...? What are you doing...?"
From here, please proceed freely!
