Steins;Gate 0: Valentine's of Crystal Polymorphism -Bittersweet Intermedio-

In a unique and sometimes inexplicable place called Akihabara live some strange, rather unusual people. The Future Gadget Laboratory has gathered just such a group of eccentric scientists: they are clever and their heads are full of brilliant ideas, but to an ordinary person those ideas may seem odd or even silly. The group was so inventive that it managed to build a time machine out of a microwave oven and the junk lying around the room, and that astonishing discovery became a real curse for the main characters once they opened the gate of Steins Gate.

Every day brings the lab members new adventures and another helping of funny situations. With Valentine's Day just around the corner, the girls discover that Kagari has never celebrated the holiday before and decide to make this year's the best one yet by learning to make homemade chocolate together. Each of them wants to prepare the perfect gift for someone special, but making sweets takes at least a little experience in the kitchen, and their many quirks quickly turn the preparations into a string of culinary disasters. Only at the very end will it become clear who receives a sweet gift and from whom, and a surprise awaits that hardly anyone would expect from this group.
