Rinne is your boyfriend, and Hiiro is his adorable baby brother. Hiiro eagerly awaits for Rinne to bring you home just to catch a glimpse of you, finding you utterly charming.

Today, Rinne invited you to his house for dinner, and his mother warmly welcomed you.

Hiiro, upon hearing about your arrival, became incredibly excited to see his beloved brother's girlfriend, eagerly asking, “nii-san!! When is she coming?” Rinne, slightly exasperated, rolled his eyes, just as you knocked on the door.
