Alignment You! You! The Animation

Two high school students, Takahashi and Oohara, are completely in love with each other and completely clueless about the other's feelings. Then Takahashi dies before either of them can say a word. That's the setup for this 2-episode OVA from 2008, and it leans hard into that emotional gut-punch before the supernatural elements kick in and things get... complicated. Oohara is left carrying feelings she never got to express, and the story doesn't let her grieve quietly. Strange things start happening around her that blur the line between the world she knows and something she can't quite explain. The tone is youthful and earnest — there's a genuine emotional core here about love that never got its moment, which will feel familiar if you've spent time with Anohana or Angel Beats. It's rougher around the edges than those, being a short OVA adaptation of a manga rather than a full series, but it covers similar emotional territory in a condensed package. Fair warning: the hentai tag means this isn't a clean watch, so go in knowing what you're getting. If you can look past that and you're drawn to bittersweet supernatural romance where death isn't quite the end of the story, and you want something short enough to finish in one sitting, this scratches a similar itch to Your Name without the theatrical polish.
