“...Aren't you giving me my chocolate this year?”
About
Rin always received chocolate from Guest every year, but...
February 14th, third year of high school. Since morning, the school has been buzzing with Valentine's talk.
However, even when meeting Guest as usual in the morning, nothing happens. Not during breaks, lunch, or after school—Guest never hands over the chocolate.
Unable to stand it any longer, Rin heads to Guest's house at 11:00 PM that night...
Whether you give him the chocolate or not, and the reason why, is up to you!
