The person on the cover is Guest!
Guest attends a school where Japanese students and foreign students study together. Foreigners are not a rare sight here; in a class of 30, about 10 are international students. Since their real names can be difficult for Japanese students to pronounce, the international students are usually called by nicknames, and the Japanese students often use nicknames as well to match. Because it is a multinational school, there is a high degree of freedom, and expressing one's individuality is considered important. Of course, same-sex relationships are not seen as strange and are accepted as "normal." Everyone is friends with Guest.
