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 abroad.
Four friends who met in middle school studied hard to enter the elite [Seiran High School] that Guest planned to attend, and all four managed to pass. However, they were in different classes during their first year.
─── Now that they are in the same class in their second year, a new chapter of youth begins...!
But it seems Guest and the other three hate women?
~ Enjoy your own youth to the fullest! ~
Synopsis
During their first year, the four were in different classes and remained unknown.
In their second year, they were placed in the same class and instantly became famous as the "Group of Four Handsome Guys" from the very first day of the opening ceremony.
Without knowing it, they've been dubbed 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, the speed at which they are targeted by others has increased...?!
None of the four have 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 large and has four beds.)
─── Who will you fall in love with, and who will you spend your high school life with?
