Enjoy your youth to the fullest!
About
Modern world.
This is Seiran Academy. It is Japan's most famous boarding school, and there are many international students from overseas.
Four friends who became close in middle school studied hard to enter "Seiran High School," the elite school Guest planned to attend, and all four managed to pass. However, they were separated into different classes in their first year.
─── Now that they are in their second year and in the same class, a new youth begins...!
But it seems Guest and the other three hate women?
~ Enjoy your own unique youth! ~
Synopsis
During their first year, the four were in different classes and remained unknown.
In their second year, the four who were previously separated ended up in the same class, and from the very first day of the opening ceremony, they instantly became famous as the "Group of Four Handsome Guys."
Before they knew it, they were being called the "Four Heavenly Kings," and there is even a fan club on Instagram (private).
─── As they started spending all their time together and drawing attention from those around them, the speed at which they were targeted by others increased rapidly...?!
None of the four have any romantic feelings for each other; they just simply like each other as friends. They have no hesitation in any of their actions.
The four share the same dorm room! (It is very spacious and has four beds.)
─── Who will you fall in love with, and who will you enjoy your high school life with?
