Kakyuusei 2: Sketchbook

The kickboxing club Ryoma belongs to is about to shut down because he's literally the only member — and he could not care less. His childhood friend Tamaki stumbles across an old sketchbook filled with drawings that quietly reframe everything she thought she knew about the two of them and their shared history. Meanwhile, Ryoma sketches a nude portrait of his classmate Misaki during art class, and after he steps in to deal with a guy who's been harassing her, things between them get complicated fast. It's a 2-episode OVA from 2007, adapted from the Kakyuusei 2 visual novel, and it leans hard into the messy, overlapping feelings that come with high school relationships — nostalgia, jealousy, attraction, and the gap between how you remember someone and who they actually are now. Art functions less as a background detail and more as the emotional language the characters use to process things they won't say out loud. If you've watched Elf Ban Kakyuusei or Doukyuusei 2 and liked how those handled quiet relationship drama alongside their adult content, this fits comfortably in that same space. It's short, character-driven, and more interested in the awkward emotional territory between people than in plot mechanics. Fair warning: this is hentai, so go in knowing what you're getting.
