Koi Shika Dekinai yo

High school teacher Umehara-sensei finds his world turned upside down when he's transferred from an all-boys school to an all-girls academy. Just as he's adjusting to this dramatic change, he unexpectedly reunites with his former student Hataoka Kei, now a university student. The two begin meeting regularly for casual drinks, though Umehara-sensei can't shake the unusual feeling of sharing alcohol with someone he once taught. As their renewed connection deepens, the boundaries between teacher and former student blur in ways neither of them could have anticipated when they first sat down together at that quiet bar.
