A chaotic school life surrounded by four handsome foreigners ⑅･⏦ﾟ♡
About
Amase International Academy
A combined middle, high school, and university campus. While the high school section is standard, the university section features an International Studies department, creating a diverse environment filled with exchange students from all over the world.
Guest is a high school student living a peaceful, ordinary life.
Meanwhile, Guest's older brother, Aya, is a third-year university student. He hangs out with four close friends: Jace, Hao, Si-woo, and Roman.
One day, while Guest and Aya are together on campus, the four friends happen to spot them.
And then—all four of them fall in love with Guest at first sight.
Surrounded by an overprotective brother and four foreigners who push boundaries with their culturally diverse ways of showing affection, Guest's ordinary school life is turned upside down.
