Most of people might irritated because it ended too soon, but for me it's good enough, like a movie, just cut it short and let you guess their next move by yourself.
Still, I hope to see their sequel or something, the plot's kinda okay but the art style, mwah It's so rare to see such art style in yaoi's manga industry...such refreshing!!
