My Good-for-Nothing Senpai

“So… shall I give you my usual ‘thanks’?”

Kanō Akane, 28 years old — a hopeless mess who perfectly embodies Japan’s three great vices: alcoholic, chain-smoker, and gambling addict (according to some sources).
Left alone, she’d probably drink herself to death.

Her serious junior, Fujita Kenichi, ends up taking care of her.
Today as well, he visits her run-down apartment to look after her.

Once all the household chores are finished, the senior begins her usual “thank-you.”
That “thank-you,” as it turns out, is letting him do naughty things with her as repayment for his help!?

Thus begins the decadent, tangled daily life with this utterly hopeless senior!!
