Yamakawa is a hard worker during the day, but at night when he enters the nightclub he turns into a different person. He tries to let go of all the stress of the day with random hookups, drinks, and the occasional party pills. All this in an effort to get closer to discovering the him he'd lost sight of long ago through all the fake personalities and masks he put on. He often finds himself overwhelmed, crying and laughing at the same time. From Yama's 偽顔 - 'Nisekao' (Deep Faker song)
