This bonus OVA for Steins;Gate 0 steps aside from the main plot for a Valentine's Day at the Future Gadget Lab. At Faris NyanNyan's urging, the lab's women gather at her home to make handmade chocolate together, with Suzuha Amane, Kagari Shiina and the others each preparing a gift. A lighthearted interlude set during the series' run, it assumes familiarity with Steins;Gate 0 and adds no time-travel developments.
