I don't understands spanish but based on the picture I guessed as much where the story leads to. My guess was right all along, Misonoi was a SPY and Saena finally figured it out but this arc hasn't end yet it seem, there's more story coming. I'm a perfectionist too so I always put everything in the order even folder in my computer. So its understandable if Saena suspect Misonoi after looking one of those 'josei case' CDs was out of order. People who thinks there's RAPE possibility can rest easy now, there's no such thing. But its might be true that he put sleeping pill in her food seeing he always deliver Saena some food to her apartment even if Saena refuse to let him in bcause she focusing hard in the case. Now, I'm just hoping that even if Misonoi tricked Saena from the beginning, he fell in love somewhere along the way but seeing Saena personality 'stubborn as iron', she is one 'never forgive never forget' type, Misonoi just give up and left and by the time Saena found out that she pregnant it was too late, he is nowhere to be found.
