A girl shows up claiming she's a god with thirty days left before the world ends, and somehow the real story isn't about the apocalypse, it's about whether you'd waste those thirty days on someone else instead of yourself. Youta starts as the kind of person who'd ignore a literal deity if it interfered with his exam schedule, then gets pulled into this girl's chaos anyway because she won't leave his house. The show pivots on a knife's edge between romantic comedy and genuine dread, never letting you settle into either one. It builds toward something that feels earned because the characters had to choose each other knowing exactly what was coming. By the finale, you're not watching a countdown to apocalypse, you're watching two people decide what matters in the time they have.

Youta is a high school student grinding through summer prep, laser-focused on acing his college entrance exams. His routine shatters when a girl named Hina approaches him claiming to be a god who knows everything. She has one piece of information that can't be ignored: the world ends in thirty days. Youta's skeptical until Hina proves her powers aren't just talk. She predicts events with impossible accuracy, leaving him with no choice but to believe. What should be catastrophic news becomes something stranger when Hina decides to stay at his house for the countdown. What follows is a collision between Youta's ordinary life and something genuinely cosmic. As summer days tick away, Youta, Hina and their friends set out to make memories before the end arrives. The show mixes comedy, drama and romance with a science fiction premise, asking what relationships mean when time is running out.
