Hajimete Nante, Kiitenai! Ichizuna Cafe Tenin no Ubuna Koigokoro

Waka, an office worker, finally turned 30 last month. Although her days are filled with work, she has no desire to fall in love or get married… But when Waka drank too much after work one night, she wakes up the next morning to find herself in a hotel room with a handsome younger man! He wasn't very good at sex though…

She thought she’d never see him again. But she ends up running into the man, Nao, who works at her favorite café, once more.
