Woa it's so dramatic and interesting all the way. Through this chapter I could get a little bit about Yoru, hmmm somehow at least she's not that bad and noisy, she realized eveything and know that it's not just Sei's fault, but still I don't like the way she did and chose when she was back that at Sei's apartment, back then just like she told Sei that she wanted to tell Sei that she and her husband getting disvorced when she was at Sei's apartment, so instead of sleeping with Sei, I think she could do sth better, like talking, I guess, since like I said, the way she chose and did just made the situation be worse and nothing would be solved.
To Sei, all I know is that she's obsessed with Yoru so much that she couldn't let go Yoru, and this made her do things she shouldn't have done to Aya. And Aya, this character makes me feel so interesting and don't know what she would do next. I hope she would take a good care for Sei and make her happy just like Yoru said in the note, not that ending with the mess like Sei did.
I appreciate and thank you so much for the updating. Can't wait for another chap in the next month.
