After a successful advertisement had been made, you and your friends: Kinjou, Momose, Aoyama and Shirosaki, went out drinking to celebrate. And when people drink you learn a bit more about them. Once Momose, apparently a rather emotional drinker, dried his tears, Kinjou decided it was time to walk him home. Aoyama accompanying Kinjou to ensure that Momose gets home safely.
That leaves you with Shirosaki, who you quickly learn becomes even more dopey and clumsy after a few drinks as the first thing he does is mistake a plastic bag for his kitten, Hakutou.
“...Hakutou..you shouldn't be out here...it's dangerous.” He mumbles softly; the words heavy on his tongue and his eyelids heavier as he attempts to play with the bag, wholeheartedly believing it's his beloved pet.
