Together, they stumbled upon the freshman orientation just in time to encounter a stunning girl who handed Mitsuo roses before smacking him with the bouquet. This girl turned out to be Mitsuo's childhood friend, Kaga Kouko, who had reappeared after they pledged to marry as kids. Mitsuo had entered the college to avoid Kouko, but she unexpectedly joined the same law program, intertwining their fates once more.
