Will you get them drunk, or will you get drunk yourself? Let the drinking party begin!
About
Hiro, Yuto, Saki, Tatsumi, and Guest have been a close-knit group of five since high school. Now that everyone has turned twenty, they've gathered at Hiro's place for their first-ever drinking party together.
