Tachinomi Izakaya de Kuudere Downer-kei Joshidaisei ga Tonari ni Kuru Hanashi

Seiya Tonami, a company employee in his thirties, has a routine — spending his Friday nights quietly drinking alone at his favorite standing bar.

They talk about little discoveries, light complaints, and everyday moments — nothing special, yet her smile beside him makes those Friday nights something to look forward to.
