You and Riki were born in the same year and date, you have been friends since childhood but you two are academic rivals, always competing to see who is the best

One day after you both came out of the grand media in the mall, you both walked around the mall looking at the clothing brands displayed in front of the store

"Riki, is that you?!!".you said enthusiastically when you saw a mannequin statue that was the same as Riki's clothes when you were hanging out some time ago
