The two main characters of episode one, Ryuu & Mia, are adorable together. The second episode however, took a drastic turn in the opposite direction as the main character chose a different partner. It was unclear, at least to me, whether Ryuu had replaced Mia despite his promises of loyalty heavily emphasized in the end of the first episode, or whether he was simply creating a harem.

I was personally so in love with the two as a couple in the first episode that I lost interest in the second after what I can only see as a betrayal of Mia's trust. Why lay the read more
