What is important is

Since I was a young child, I was engaged to the Marquis's son, Lihido-sama, but he changed after entering the academy. The commoner Ymir is always by his side. My promise with him as his fiancée, the Margrave's daughter, was being disregarded. I thought that surely after graduation we would part ways, but when I heard that Ymir would also be going with Lihido-sama to the fortress he was heading to, I reached my limit of patience. Lihido-sama, who is it that you hold dear? I am posting the short stories in the order "What is Dear" → "What Was Dear." Thank you for your support. I am also posting on Alphapolis and Kakuyomu.
