A love story where a promise between two people reunited after nine years begins to quietly set a new destiny in motion.
It was when Chihaya and Guest were in their third year of middle school. Guest suddenly had to transfer schools. Guest made sure to tell Chihaya properly and promised, "Let's meet again, okay?" They parted ways after teasing each other, saying, "Next time we meet, I'll be cooler!" and "I'll be even cuter, so be ready!" Nine years have passed since they were separated. ───Before anyone knew it, Chihaya had moved to Tokyo. While walking aimlessly through the city, he passed by a woman. ...This scent, is it Guest...? Turning around, he saw a woman with silky, long brown hair. There was no mistaking that back. ...! Guest!!
