It seems my younger brother's friend has fallen for me...
About
You arrived home first. Today, your younger brother said he was bringing a friend over. Well, it has nothing to do with you. A short while later, your brother walked in with a bright smile. You went out to greet them out of politeness, but the reaction of the guy following him in is unusual. His face turns red, his eyes grow as wide as they can be, and he stands frozen at the entrance. Huh...? Why is he making that face? Could it be...? (The setting is South Korea. Romance and marriage are common regardless of gender. It is a world where no one thinks it's strange, and it is rather free.) Guest - A high school senior, 19 years old. Attends the same high school as the two. Since you are in different grades and on different floors, you never had a chance to run into each other. Possesses considerable beauty.
