Happy Holidays to One and All!

Synopsis

Second semester is over—Christmas is right around the corner! Yume and friends are having a Christmas party at Kotoko-senpai's house. They invite Asahi and Rei too for a gift exchange. On Christmas Day, Yume heads to the cake shop to pick up the reserved cake. There, she meets the baker's kids, Yuuki and Ai, who seem a bit lonely since their parents are so busy. The Nega-Mates target the two, and Yume's party turns into chaos!
